I’ve just taken delivery of the latest Himo ZB20 Max folding electric bike, and in this review, I’m going to be covering all aspects from delivery, how the bike was packed and importantly give you a detailed appraisal of the components. Plus, I’ll be giving you my thoughts on performance, comfort, handling (on and off-road) and real-world battery range.

I plan on using the ZB20 Max as a general runabout and will be adding a cargo trailer for shopping trips and other errands – I’ll be posting regular updates here as things progress. I’ll also be doing a couple of YouTube videos covering unboxing, assembly and riding.

Brand Summary

Anyone familiar with the Himo brand of electric bikes will know they offer excellent quality at an affordable price. I’ve previously test-ridden a few e-bikes in their range and have always been suitably impressed. This latest version is fully EN15194 compliant meaning it meets the legal requirements of a pedelec in the EU and UK.

Himo are the first Chinese brand to have full CE certification on all of their products. All Himo E-Bikes also conform to the important EN15194 – this covers electrical and mechanical safety standards.

Himo are really putting a big emphasis on looking after their European customer base, with a 3000 square metre central technical service centre in Germany and three maintenance centres in Germany, the UK and Poland. There’s also a decent warranty of 12 months on electrical components and 10 years on the frame.

For quick shipping to all European destinations, Himo have distribution warehousing is the following locations: Germany (Brushal), Poland (Mazowiechie), United Kingdom (Lancashire),Spain(Madrid), Italy(Rome).

Delivery and Packaging

I received my Himo ZB20 Max within five working days and the bike was incredibly well-packaged in a large box. All the key components were well protected, as was the frame and any other vulnerable parts.

I’ll be shortly uploading a video to YouTube of the unboxing – this bike is quite heavy and I would certainly recommend two people to make the task easier.

The ride – first impressions

It’s been a while since I’ve ridden a fat tyre e-bike and it took a bit of getting used to. I usually ride a road bike and hybrid e-bike, and this felt cumbersome in comparison. But, this is not an electric bike designed for riding at 25mph and is better suited to cruising at lower speeds.

As expected there’s a lot of noise from the tyres (akin to a Land Rover) and the steering initially felt a little nervous. Once I’d gotten the hang of it, everything was fine.

Performance was better than expected. The pedal assist is very smooth and doesn’t kick in with a jolt, but builds progressively. I was also very impressed with the quietness of the motor. Riding up a climb with an average 6-8% gradient was fairly effortless.

The brakes performed as expected, they stopped the bike quick enough and I’m sure they’ll improve once bedded in properly. Gears shifted well using the old-style Shimano thumb shifter.

Comfort was another level! The combination of the fat tyres, front suspension and padded saddle made for a very plush ride. I’m looking forward to putting in quite a few miles on the ZB20 Max, and will update this article in future with real-world battery range.

Electric components

  • Motor: The Himo ZB20 Max uses a brushless geared 250w rear hub motor that’s powered by a 48v 10.4Ah battery. This all-new model is fully EN15194 compliant, meaning it’s legal to use in the UK and EU countries. The rated torque is 32Nm which is about right for a 250w hub motor this design.

  • Pedal assist sensor: Pedal assist is cadence-based, meaning it’s activated by pedal crank rotation. The Himo has an updated motor control unit which has an improved pedal assist algorithm, making the assist feel smoother and more natural.

  • Display: This bike features the excellent 500s display unit which is clear to read and has great functionality. There are 3 power assistance modes to choose from, a battery indicator, power indicator, speedometer and trip function. This display is IPX7  waterproof meaning it will be fine to use in heavy rain. In my experience, this particular display is generally very reliable, and even if were are issues (outside of warranty) a replacement is cheap and easy to source.

  • Battery: There’s a decent 48v 10.4Ah battery, which fits neatly inside the frame (out of harms way). This battery has all the latest BMS safety features including overcharge / discharge protection, over current, temperature and short circuit protection. A 48v battery will achieve 250w by drawing less current (amps) when compared with a 36v system – this means the motor will run cooler and be more efficient (plus increased reliability).

Bike components

  • Gearing: A Shimano Tourney 6-speed derailleur with thumb shifter, provides reliable gear shifting. There’s a 14-28t freewheel and large front chainring giving a decent gear range for a bike or this kind.

  • Brakes: The front and rear mechanical disc brakes work just fine, but as I’m going to be towing a trailer, I’ll be upgrading to hydraulics – I will be fitting a pair of Zoom HB-100 hydro-mechanical brakes which offer a substantial improvement on braking for not a lot of money.

  • Suspension: There’s a decent front suspension fork of the coil-sprung variety, which will be ideal to soak up potholes and rougher terrain. These forks have a hydraulic lock-out function and can also be adjusted for preload. They’ll be okay for moderate off-road riding, but not big jumps.

The suspension fork works very well and can be locked-out
  • Wheels and Tyres: The 20″ wheels look tough and with the 4″ wide tyres I’m expecting the ZB20 Max to be a versatile machine capable of riding off-road on difficult terrain. I plan on putting the Himo through its paces by tackling a long off-road route on Dartmoor (in the UK).
  • Accessories: The ZB20 Max comes with a useful array of accessories including some very nice metal mudguards, kickstand and lights. Plus, there’s a tyre pump which fits neatly inside the seat post tube.
  • Frame and finishing kit: I love the frame, it looks and feels like it could stand up to a lot of abuse – it’s covered by a 10 year warranty and has undergone stringent safety tests. The seat post has plenty of adjustment for taller riders – I’m 185cm and there was plenty of adjustment left. Finally, the handlebars are a little narrow for my liking, but this is to facilitate easy folding. As I won’t be folding this much, I’m going to fit some wider MTB handlebars. The saddle is good quality and has plenty of padding, adding to comfort.

Who is the Himo ZB20 Max E-Bike aimed at?

The Himo ZB20 Max is so versatile it’s going to appeal to a broad range of riders. The Himo will make an excellent daily commuter e-bike or could be used for weekend leisure rides. Thanks to the fat tyres, the ZB20 Max will be ideal for riding on snow, sand or mud. It would also be great as an urban e-bike – I’m going to be using mine as a general runabout, with the odd excursion up to the moors.

Folding the ZB20 only takes a matter of seconds, but be warned – it’s very bulk and heavy at 28kg and I personally wouldn’t want to try carrying this on public transport.

Where can I buy the Himo ZB20 Max?

Fortunately, the Himo ZB20 Max is available in most countries. I have included links below to all the main eBay stores. Plus, links to the popular Chinese e-commerce platforms Geekbuying and Banggood – these companies usually ship from the EU and UK.


My initial impressions of the Himo ZB20 Max are very favourable. I can’t fault the finish and build quality, it comes across as very tough and well-built. Over the coming weeks, I’ll be expanding upon this review with more  photos. I plan on tackling some longer rides and it’ll be interesting to see how much range I can squeeze out of the battery.

It’s a great-looking bike and is available in the matt grey paint of my bike or a nice sand colour (above). The frameset looks robust and it’s good to see a 48v system being used. The performance is very good for a 250w considering the heavy weight of bike (and rider), and I’m very impressed with the smoothness of the PAS and very quiet motor.

The only downside to this bike is the weight and size – it may be a folding e-bike, but it’s a beast of a machine. It looks a lot bigger in the flesh and it’s very heavy. In my opinion it’s not really going to be practical to cart around town on public transport, unless you’re a powerlifter!

When compared with the competition, the Himo ZB20 Max is great value for money and I’m looking forward to putting plenty of miles in on mine.  If you’re looking for a versatile, all-terrain folding electric bike, then I would highly recommend the Himo!
