Best eBike Conversion Kits in 2021

This post contains affiliate links, to find out more information, please read my affiliate disclosure

Electric bikes are increasing in popularity year on year, and 2021 is shaping up to be one of the best yet. Despite the overwhelming array of e-bikes currently available and a massive reduction in prices, the DIY ebike option is still very popular amongst intrepid enthusiasts.  In this article I have selected some of the best ebike conversion kits currently available – I have personal experience installing a lot of these kits, so my appraisal will be based on personal experience.

Summary

For the benefit of this article I will be breaking down the kits into two sub-categories: Best mid-drive ebike conversion kit, best rear wheel hub motor kit. Please check combability with your donor bike and if you have any questions, leave a comment below – I usually reply within 24hrs.

For more information on ebike conversion kits, and choosing the right one for your needs, please read my comprehensive electric bike conversion kit buyers guide.

***Please check the legality of these kits in your country before making a purchase – in the UK and EU anything that produces more than 250w continuous power and 15.5mph (25km/h) is classed as a moped and subject to the same rules and regulations. US Federal law allows up to 750w and 20mph.

Best ebike conversion kits – Mid-Drives

Mid-drive electric bike conversion kits are by far the most refined, in terms of power delivery and efficiency. A good 250w mid-drive will easily outperform a 500w direct drive hub motor in every aspect.

There are two main players in the plug and play mid-drive motor market: Bafang have dominated the DIY ebike conversion kit market for years with their BBS series of motors, and more recently Tongsheng have become incredibly popular with their torque-sensing TSDZ2 motor.

Although both motors are similar in many ways, the way they produce electric assist is quite different. The Bafang uses a simple cadence sensor, which measures pedal rotation (and speed). The Tongsheng TSDZ2 motor uses a more sophisticated torque sensor – this measures the amount of force being applied to the pedals and gives the rider assistance in proportion to that force.

Which motor is best suited to you really depends on your requirements as a rider. I find the Bafang is generally more suited to riders who have knee problems, as the pedal assist acts very much like an on/off switch. You do not need to exert any discernible force to get the motor to start. Once you’re on the move, you can effectively ‘ghost pedal’ which means, you can spin the pedals without putting in any effort (although this depends on the power rating of the motor you have).

✅Link to Tongsheng TSDZ2 (trusted vendor on Aliexpress)

The Tongsheng on the other hand requires a small amount of force to be exerted through the pedals before the assist will kick in. This torque-sensing effect produces a very smooth and intuitive pedal assist, making the motor feel more like an extension of your own abilities. Basically it takes your pedalling effort and amplifies it. You cannot ghost pedal with the TSDZ2, as the motor will not assist – you will only get assistance in proportion to your effort.

I personally prefer the torque sensing assist of the Tongsheng, as it feels very similar to high-end units like the Bosch or Shimano Steps ebike systems. For a direct comparison between the two motors, read the full article here.

Anyway, on with the list. I have also included the lesser-known Lingbei mid-drive, and although I have yet to test one out, they do have good customer feedback.

1. Bafang Mid-Drive E-Bike Conversion Kit

✅Link to the Bafang e-bike conversion kit (trusted vendor on Aliexpress)

It was Bafang that got the ball rolling with plug-and-play mid-drive e-bike kits back in 2014. In the ensuing years, this motor has gone from strength to strength, undergoing various upgrades to the electronics. A lot of people have a love / hate relationship with these motors ( including me!). They are fantastic when they are running well, but can be a pain when they go wrong.

***18.6.2021 BAFANG LAUNCH THE NEW M325 AND M625 MOTOR KIT***

The Bafang is available in various guises, I have listed the power outputs below for each model:

633w
BBS01 350w 36v36v (42.2v x 18A)759w
Please note: Due to the firmware programming on the BBS01B 250w, the power may peak at around 600w when the motor is under load going up a steep hill, but will settle back to 250w when pedalling on the flat.

1632w
BBSHD52v (58.8v) x 30A1764w
The voltage figures in brackets are for a fully-charged battery. Note: As the voltage drops, so will the power.

The BBS01 250w / 350w is the same motor, just with different firmware settings in the controller. Although physically the same, the BBS02 has a more powerful motor, and can handle 48v at 25A maximum (or 52v if you’re feeling lucky!), the 500w version has 18A maximum current and there is a 36v 500w version that uses a different controller.

These motors use cadence based pedal assist, meaning that the motor provides assistance based on pedal rotation (and cadence speed). I personally prefer the torque sensing pedal assist of the Tongsheng TSDZ2, but one of the great things about the Bafang is the ease at which it can be reprogrammed. All you need is a USB lead and the software and you are good to go. The software is very user friendly and there is plenty of information available on programming (particularly endless sphere).

What’s included in the kit

  • Bafang BBS01 / BBS02 / BBSHD mid-drive electric motor
  • LCD Display – B&W C961 / C965 or full colour P850c / P750c / DP-C18
  • Speed Sensor with spoke magnet
  • Motor fixing plate (and fixings)
  • Motor lockrings
  • Wiring loom
  • E-Brakes (for cable brakes only)

Is this kit easy to install?

Any mid-drive motor installation requires the complete removal of the bike’s bottom bracket. You will need to have the right Shimano bottom bracket tool for the job, and also a decent breaker bar. Removing the bottom bracket can be difficult, but thankfully once this job is done the rest is fairly easy. Once you have removed the bottom bracket you will need to clean the area and possibly use a little sand paper to prepare the shell for insertion of the motor axle.

✅Link to the Bafang BBS02B (trusted vendor on Aliexpress)

You will need a Bafang tool to tighten the lockring. If you do not want to purchase one of these, a c-spanner will suffice, but be prepared for scraped knuckles!

If all goes smoothly it should only take around 3 hours, but it can take a lot longer, if you end up having problems removing the bottom bracket. I have a downloadable PDF installation guide available.

What bikes are compatible?

This kit is only suitable for bicycles that have a 68mm-73mm threaded bottom bracket (including Shimano Hollowtech ll or SRAM GXP) I would not personally attempt fitting one to a bike with a pressed fit bottom bracket, as you will need to machine a special shim adaptor – fine if you know a good engineer. PLEASE NOTE: There is a 100mm and 120mm bottom bracket version of the BBS01, BBS02 and BBSHD suitable for Fat Bikes.

Conclusion

Despite some of the reliability issues I have experienced with customer conversions, I still think the Bafang BBS02B 750w is one of the best ebike conversion kits available. I used a BBS02 powered bike for the best part of a year, clocking up nearly 2000 miles, and I never had even a hint of a problem. Having said that, I used the bike as a means of getting fitter, so would only use the power when I really needed it.

It seems that a lot of the problems experienced with this motor happen when they are thrashed constantly in full power mode. Thankfully there is never a shortage of spare parts available.

I have installed over a hundred of these motors, and have had a lot of happy customers. But there have been issues with controllers failing – these failures all happened on bike’s that had 52v batteries fitted.

The most reliable of the Bafang mid-drives are the 36v 250w / 350w BBS01 variants, I have only ever had one failure reported with this model.

If you can live with the potential issues, that may arise, these really are excellent motors and well worth the money!

For more information on the Bafang mid-drive kit, I have posted a full review of the BBS01 250w and the BBS02 in separate posts.

2. Tongsheng TSDZ2 Mid-Drive eBike Conversion Kit

✅Link to the Tongsheng TSDZ2 (trusted vendor on Aliexpress)

I absolutely love the Tongsheng. It is a cracking little mid-drive motor for the money. If you are after Bosch-like performance for a fraction of the price, then this is the kit for you.

As I have stated in my full review of the TSDZ2 this is a good system, and like the Bafang BBS01 / BBS02, it is available in 250w / 350w / 500w / 750w versions.

For those of you unfamiliar with this motor. It uses a torque sensor for pedal assist, meaning it will give you power, proportionate to the amount of force applied to the pedals (much like the Bosch system). The benefits of this system are, it gives you an enhanced cycling experience rather than just giving you power whenever the pedals are turned. In other words, you still have to put a bit of effort in.

What’s included in the kit

  • Tongsheng TSDZ2 mid-drive electric motor
  • LCD Display
  • Speed Sensor with spoke magnet
  • Installation spanner / tool
  • Motor fixing plate (and fixings)
  • Motor lock-rings
  • Wiring loom

Is this kit easy to install?

Mid-drive motor installation requires the complete removal of the bike’s bottom bracket. You will need to have the right Shimano bottom bracket tool for the job, and also a decent breaker bar. Removing the bottom bracket can be a right pain (literally!) but thankfully once this job is done the rest is fairly easy. Once you have removed the bottom bracket you will need to clean the area and possibly use a little sand paper to prepare the shell for insertion of the motor axle.

If all goes smoothly it should only take around 3 hours, but it can take a lot longer, if you end up having problems removing the bottom bracket.

What bikes are compatible?

This kit is only suitable for bicycles that have a 68mm-73mm threaded bottom bracket (including Shimano Hollowtech ll or SRAM GXP) I would not personally attempt fitting one to a bike with a pressed fit bottom bracket, as you will need to machine a special shim adaptor, and it’s unlikely there will be enough clearance between the motor shaft and housing

Conclusion

When I was writing my review of the Tongsheng TSDZ2 I was very tempted to make it my number one electric bike kit.

In my opinion, it beats the Bafang, hands-down in a number of areas. The chain-line is slightly better, and you could even fit a double chainring to this motor if you wanted (something that doesn’t work well on the Bafang). The other thing I like about this motor, is that it is not too difficult to pedal with the power off.

The only reason I haven’t put this kit at the top spot, is because the Bafang mid-drive is a more versatile, as far as custom programming is concerned.

The TSDZ2 may not suit everyone’s tastes, but if you are after an enhanced cycling experience, where you still have to put in some effort, then this could be the electric bike kit for you.

As with all mid-drive motors, the long-term reliability is questionable, and it really boils down to luck of the draw, and the way you ride it. Thankfully there is a good supply of replacement parts available. You will also need to purchase a separate 36v or 48v Lithium battery pack.

3. CYC X1 Pro Gen2 Mid-Drive Conversion Kit

 

cyc x1 pro

The  CYC X1 Pro offers a totally different level of performance when compared with the Bafang and Tongsheng. This is a motor for serious performance e-bike enthusiasts and should only be installed on bikes that have the highest quality components fitted.

With an eye-watering power output of 5000w and up to 250Nm of torque the CYC X1 Pro is not for the faint hearted! Manufactured by CYC Motor LTD in Hong Kong, the X1 Pro has quickly become the global leader in ultra performance mid-drive electric bike motor kits.

CYC X1 Pro is now available from Amazon

Compatible with batteries ranging from 36v all the way up to 72v (for maximum power) this motor is designed to turn your mountain bike in to an off-road speed machine and uses a sophisticated torque sensor to provide incredibly smooth pedal assist over a range of power modes.

cyc x1 pro electric bike motor

Where is wins hands down over the Bafang and Tongsheng is not just its staggering performance but its compatibility with other bottom bracket sizes – the CYC X1 Pro is available in Pressfit BB92 and 100mm threaded BB as well as the regular 68mm-73mm BB version (for the torque-sensing model) and it’s also available with a cadence-based pedal assist in the 68mm-73mm and 120mm version.

cyc x1 pro gen2 e-bike kit

There is a fully customisable smartphone app that means you can really fine-tune the performance to suit your needs, as well as two rider modes and up to nine assist levels – in low power mode it feels very much like a regular mid-drive electric bike and produces a very smooth and intuitive level of assist, switch to max power mode and it turns into a completely different beast!

cyc x1 pro smartphone app

A word of caution – This kit is strictly intended for use off-road on private land and should not be installed on a bike that is going to be used on the road – the performance in full power mode is more akin to an electric motorcycle.

Conclusion

If you’re after serious performance conversion kit for off-road use, there’s simply no other kit quite like this. The performance is remarkable and is guaranteed to provide a massive grin factor! But this is an electric motor kit that’s intended for serious enthusiasts only – you’ll need to be competent in bicycle maintenance to install it and preferably it should only be installed on a bike with high quality brakes and other components. The CYC X1 Pro should not be purchased for a bike that is going to be used on the road.

Conclusion – What is the Best DIY Mid-Drive e-Bike Kit?

So, is there a clear winner for the accolade of best mid-drive electric bike conversion kit?

I know, that I have my personal favourite. But ultimately we are all looking for something different and have our own expectations of what makes a good e-bike. The CYC X1 Pro has been around for a couple of years now and is an amazing electric bike kit, but it’s aimed at a very niche market where off-road performance takes priority over day to day use.

For some riders, outright speed, and the ability to zip along at 30mph without doing too much pedalling is the ideal electric bike, whereas for me personally, I want the bike to feel like an extension to my own abilities.

If I had to choose, I would go for the Tongsheng TSDZ2. For me it provides the right balance of power, combined with the intuitive, torque-sensing pedal assist.

I also love the Bafang BBS02B 750w. The great thing about this motor, is that it’s a real Jekyll and Hyde. It is quite mellow in power level 1, giving you just a little help when you need it. But If you hit power level 9, it becomes a powerful beast, capable of over 1400w of peak power (with a 52v battery fitted).

Ultimately, it’s your decision, but make sure you check your bikes compatibility first. Next we move on to rear wheel hub motors. These are generally a lot cheaper and a lot more straightforward to install.


Best ebike conversion kits – rear wheel hub motors

If you are looking for a more affordable and easier to install electric bike conversion kit, then it would be worth considering a rear hub motor kit.

These kits usually come laced into a rim, and all you need to do is replace your bikes regular wheel with the motorised wheel and fit ancillary components like the display, pedal sensor, motor controller (ECU) and, of course the battery!

What are the benefits of a rear hub motor? Well, they are usually cheaper than their mid-drive counterparts and (in my experience) generally more reliable. Most hub motor kits only use a cadence sensor, but there are some kits available that use a more sophisticated torque sensor.

You won’t have anything like the efficiency of a mid-drive (or torque) which means you will need to consider your mileage requirements as a hub motor will get through a battery quicker than a mid-drive.

Here is my selection of the top 5 best rear wheel electric hub motor conversion kits.

1. Bafang 500w 48v Rear Wheel e-Bike Conversion Kit

bafang hub motor ebike conversion kit
✅Link to Bafang hub motor conversion kit (trusted vendor on Aliexpress)

Bafang have been a global leader in electric bike components for some years now and their geared hub motors are among the best available. They are so good, in fact that a lot of e-bike manufacturers uses their hub motors in factory electric bikes.

Unlike their direct drive counterparts, the geared hub motor is not only more efficient, but produces a lot more torque (very important for hill climbing).

The Bafang hub motor is generally also very reliable, while at the same time offering top class performance. The motor is a little nosier due to the planetary gears, but the noise minimal.

The 500w 48v Bafang kit contains everything you need apart from a battery.

What’s included in the kit

  • 500w 48v Bafang 8fun geared hub motor – laced into a 24″ / 26″ / 27.5″ or 28″ wheel
  • Motor controller
  • Motor controller bag
  • LCD Display
  • Thumb throttle
  • Pedal assist sensor
  • E-Brakes  (for cable brakes only)
  • Motor to controller extension cable and wiring loom

Is this kit easy to install?

Installation is the same as for the other hub motor.  You will need certain tools, and a bicycle stand will definitely come in handy. Basically you would swap out your standard rear wheel for this one and fit the display to your handlebars. The pedal sensor fits on the left hand side (non-drive) over the bottom bracket axle, and the motor controller goes into a frame-mounted plastic box.

The connectors on this kit are of the higo type (which a waterproof) and make for a very neat installation.

On some bikes it may be necessary to file out the rear drop-outs to accommodate the larger axle of the hub motor. You should always buy a torque arm, as this will help prevent the rear wheel from popping out of the drop-outs.

This kit will require a 48v e-bike specific Lithium battery pack, with a continuous rating of preferably 20A. This will need to be connected to the controller – ensuring the red (+) and black (-) wires are not mixed up.

What bikes are compatible?

This kit is available in various wheel sizes from 24″ up to 28″ (700c). As with all hub motors, If your bike has thru-axles then this kit would not be compatible. As with all external pedal sensors, the kind of bottom bracket your bike has is important. This pedal sensor that comes with this kit would  not be compatible with a Shimano Hollowtech ll or SRAM GPX BB. If you have this type of bottom bracket then you will need a special pedal sensor.

Conclusion

The Pasion eBike 500w 48v Bafang  hub motor kit, is one of the best on the market. It is incredibly efficient, and provides loads of torque for helping you up those steep hills. Another good point worthy of note, is when the motor is switched off or on level ‘0’ you can pedal your bike normally, without any increase in drag or resistance.

The other great thing about these motors is their durability. Geared hub motors can sometimes suffer from wear of the planetary gears (which are usually made of nylon), but with the Bafang hub motor it doesn’t seem too much of a problem – be warned though. If you choose upgrade this motor with a more powerful controller and battery, it will increase the likelihood of premature planetary gear failure.

As with all hub motors, you will need to check and tighten the spokes regularly, and definitely make sure you fit a good puncture resistant tyre like a Schwalbe Marathon Plus – to save on time consuming roadside puncture repairs.

I have fitted a lot of these kits, and to date I haven’t experienced any long-term issues.

This is certainly not the cheapest electric bike conversion kit available, but the Bafang 8fun hub motor is smooth, powerful and generally reliable, plus  I like the flexibility of a geared hub motor, as they are much easier to pedal with the motor switched off.

ebikeling 36v 500w front or rear geared hub motor electric bike conversion kit

This kit 36v 500w ebike conversion kit is supplied by Ebikeling – an American company based in Illinois.

It uses a geared hub motor, very similar in design to the Bafang motor. These kits are available in front or rear wheel versions and popular 26″ or 700c wheel sizes.

What’s included in the kit

  • 500w 36v Ebikeling geared hub motor – laced into a 26″ or 28″ front or rear wheel
  • Motor controller
  • Choice of LED or LCD display
  • Choice of thumb or twist throttle
  • Pedal assist sensor
  • E-Brakes  (for cable brakes only)

What bikes are compatible?

This kit is available in 26″ and 28″ (700c). As with all hub motors, If your bike has thru-axles then this kit would not be compatible. As I have mentioned previously, the external pedal sensors supplied with most of these kits are not compatible with a Shimano Hollowtech ll or SRAM GXP BB. If you have this type of bottom bracket then you will need a special pedal sensor specifically made for this Hollowtech ll.

Conclusion

The Ebikeling 36v 500w hub motor is an excellent quality motor for the price. It is also very efficient and robust, plus it provides a lot of torque for such a small motor (making those hills a doddle).  As with any geared hub motor you can pedal your bike easily with the motor off, without any increase in drag or resistance. The top speed is approximately 20mph, which is within the US federal law requirements.

Maintenance is the same as other hub motors, you will need to check and tighten the spokes regularly, and preferably fit a good puncture resistant tyre like the e-bike rated Schwalbe Marathon Plus – to save on annoying roadside puncture repairs.


3. Ncyclebike 48v 1500w Electric Bike Conversion Kit

1500w rear wheel electric bike conversion kit
✅Ncyclebike 1500w e-bike conversion kit (trusted vendor)

The Ncyclebike 1500w ebike conversion kit uses a simple ‘direct drive’ hub motor. Direct drive hub motors are the simplest and most reliable form of electric propulsion for a bicycle. I have written an article about these motors and how they work.

If you want to turn your ordinary mountain bike or hybrid into a fast electric bike, then this kit is a great starting point.

What’s included in the kit

  • Direct drive electric hub motor laced into a 20″ / 24″/ 26″ / 27.5″ / 28″ rear wheel
  • 48v 35A smart controller
  • Motor controller bag
  • LCD Display
  • Throttle
  • Pedal assist sensor
  • E-Brakes
  • Cable ties

Please note: This kit does not include a battery – you can find a list of electric bike batteries here.

Is this kit easy to install?

Installation is fairly straightforward, you will need certain tools, and a bicycle stand would come in handy. Basically you would swap out your standard rear wheel for this one and fit the display to your handlebars. The pedal sensor fits on the left hand side (non-drive) over the bottom bracket axle, and the motor controller goes into a frame-mounted bag.

On some bikes it may be necessary to file out the rear drop-outs to accommodate the larger axle of the hub motor. You should always buy a torque arm, as this will help prevent the rear wheel from popping out of the drop-outs.

Assuming you have purchased and e-bike specific Lithium battery pack, this will need to be connected to the controller – ensuring the red (+) and black (-) wires are not mixed up.

A lot of time will be spent cable tying up all the wires, and making a nice clean and tidy finish.

What bikes are compatible?

This kit is usually available in 20″ / 24″ / 26″ / 27.5″ and  28″ wheel sizes. A Fat Bike version is also available.

If your bike has thru-axles then the motor would not fit. The other thing to consider is the kind of bottom bracket (BB) your bike has. If it is a standard square-tapered BB, then you will be fine. If you have a Shimano Hollowtech ll or SRAM GPX BB, then you will need a special Hollowtech compatible pedal sensor specifically made for this type of BB.

Conclusion

Direct drive hub motors are heavy, inefficient and difficult to pedal without power, but when you have 1500w on tap, they can be great fun! You should only install this kit on a bike with decent components, like hydraulic brakes and good suspension.

Buy similar 1500w ebike conversion kits on eBay

The motor itself should be maintenance-free, but you will need to tighten the spokes regularly, and I advise fitting a good puncture resistant tyre like a Schwalbe Marathon Plus – You do not want to be trying to remove the rear wheel at the side of the road, as it can be a right pain (and time consuming). The Schwalbe Marathon Plus is also one of the few tyres rated for e-bike use.

I have fitted lots of these kits, and there have been very few long-term issues. I personally prefer geared hub motors, but if it’s value for money you’re after, then these 1500w kits are hard to beat!

If you want to build a fairly powerful off-road e-bike on a tight budget, then I would say this kit is worth a punt, but don’t forget to factor in a decent 48v battery into the price – you will need  battery that has a continuous rating of least 30A (amps).


4. Ebikeling 48v 1200w e-Bike Conversion Kit

Ebikeling 48v 1200w front wheel electric bike conversion kit

Another great e-bike conversion kit by Ebikeling. Just like all of their other kits this 48v 1200w direct drive motor is available in front or rear wheel options, and has the choice of an LED or LCD display.

It’s true that the Ebikeling kits are not the cheapest available, but the quality is second to none and customer support from the company is also excellent.

If I was looking for a direct drive hub motor, I would much rather pay a few extra dollars, and get one of these great kits.

As far as performance goes, the 1200w 48v motor provides more than enough power to take you along at a comfortable 30mph on the flat. You can also fit a 52v battery for optimum performance. They also do a 1500w version of this motor.

Conclusion

If you’re after a high quality direct drive hub motor kit that includes everything you need apart from a battery, then this offering from Ebikeling is one of the best ebike conversion kits available for the price. The build quality and finish are excellent and the motor is guaranteed to be durable and reliable over very high mileages.


5. Voilamart 1000w 26″ Rear Wheel e-Bike Conversion Kit

 

voilamart 1000w 48v ebike conversion kit rear wheel

The Voilamart 1000w 26″ rear wheel direct drive, e-bike conversion kit offers exceptional value for money. In fact out of all the kits reviewed in this article, this one definitely offers the best bang for your buck!

Unfortunately it is only available in 26″ rear wheel format, which shouldn’t be too much of a problem as most older mountain bikes and some new ones are available with this wheel size.

mountain bike fitted with voilamart 1000w 48v electric bike conversion kit

The only thing this kit doesn’t come with (apart from a battery) is a torque-arm, I definitely recommend fitting one of these on such a powerful rear hub motor. This is a back-up safety measure and can prevent your rear wheel from popping out of the dropout.

Buy the Voilamart 48v 1000w ebike conversion kit on Amazon 

The 1000w 48v direct drive motor can be powered by either a 48v or 52v battery. If you choose to use a 52v battery, peak power will be closer to 1500w.

Conclusion

The Voilamart 1000w electric bike conversion kit is definitely good value for money. These direct drive hub motors, are generally very robust and reliable. They may not be particularly efficient, but this motor will give you enough power to hustle you along at 25 – 30mph on the flat comfortably. Definitely worth considering, if you are after something a bit faster.

You will need to purchase an additional torque arm, and the brake levers supplied with this kit are only suitable for cable operated brakes. If you have hydraulic brakes, you may want to purchase separate hydraulic brake cut-off sensors.


Conclusion – What is the Best rear wheel hub motor eBike Conversion Kit?

Having converted hundreds of bicycles to electric assist, the best rear hub motor in my opinion is the 500w Bafang. It is generally very reliable and very smooth in operation. Both of the Ebikeling kits featured above are excellent. They are well-made and you have an option of front or rear wheel hub motor, a choice of LED or LCD display and thumb or twist grip throttles. I also like the fact the company has been thoughtful enough to include the all-important torque-arm in the package.

At the cheap end of the scale we have the Voilamart 1000w rear wheel DIY e-bike kit. Although this is quite a basic kit. If you’re just after a reliable and cheap form of electric transport, then there is no cheaper way to turn your cruiser or mountain bike into an ebike.

Whatever you decide have fun and ride safe!
