Making the change from rear derailleur gears to hub gears can be one of the most beneficial upgrades you can do to your e-bike. In this article, I’m going to be looking at 5 of the best internal gear hubs for electric bikes and explore the pros and cons of such a setup.

Hub Gears vs Derailleur on an Electric Bike

There are lots of advantages to hub gears vs derailleur on an electric bike, which I have listed below in more detail:

  • Low maintenance: One of the main advantages of using a hub gear is greatly reduced maintenance schedules. Most hub gears are in sealed units that require a periodic fluid change (like the gearbox in a car). It’s a fairly straightforward job for the home mechanic or bike shop and intervals are usually several thousand miles.
  • Less risk of damage: Derailleurs can be easily damaged if you fall off your bike, they are also easily damaged if you do a lot of off-road riding. No such problem with hub gears as everything’s tucked neatly out of harm’s way.
  • Less noise: Hub gear systems are much quieter than derailleur gears, and if you can fit a Gates belt drive, they are virtually silent.
  • Potential to use belt drive: This isn’t quite so straightforward as a frame modification is required to fit a belt drive. This involves cutting the drive-side rear seat stay and installing a frame splitter for the belt to go through. This can be expensive and needs to be done by an accredited professional.
  • Change gear while stationary: There’s nothing worse than coming to a standstill only to pull away in the wrong gear. With a hub system, you can change gear whilst stationary, making them really good for urban riding.
  • Reliability: Internal hub gears are well-engineered and will usually last tens of thousands of miles before requiring rebuilding. In the case of Rohloff, the guarantee is a lifetime.

Negatives of Hub Gears on E-Bikes

There are a few negatives when it comes to using hub gears on an e-bike. In most cases, the positives outweigh the negatives, but it’s worth being aware of them all the same.

  • Weight: This is really negligible, and not really that much of an issue with an e-bike. Internally geared hubs will always weigh a little more when compared with a traditional derailleur set-up.
  • Repair: Although the hub gears featured below are all very reliable (especially the Rohloff), in the event there is an issue with the hub, it’s not going to be a straightforward fix as is usually the case with derailleur gears.
  • Wheel removal: If you’re sensible, you will have puncture-resistant e-bike specific tyres like the Schwalbe Marathon Plus fitted. But, even these aren’t bulletproof! If you do find yourself with a flat tyre, removing a wheel with a geared hub isn’t as straightforward and requires a bit more faffing about.

Can I Fit Hub Gears On My E-Bike?

This really depends on the kind of electric assist system you have on your e-bike. You can fit hub gears on an e-bike with either a front electric motor or mid-drive motor but not a rear hub motor (for obvious reasons).

You will need a chain-tensioning system and most hub gears systems feature a tensioner that looks a little like a small derailleur but its main purpose is to maintain the correct chain tension at all times.

The 5 Best Internal Hub Gears for E-Bikes

All of the internally geared hubs featured below are of the highest quality and are used either as OEM components on certain e-bikes or fitted after-market. I have personal experience with the Shimano Nexus 8 as well as the  Alfine 8 and 11 (Di2) – I’ve successfully installed the Nexus 8 and Alfine on high-powered mid-drive electric bikes without compromising reliability (of the hub).

  1. Hi Tony, great article! I have a Riese & Muller Super charger 2 class 3 top speed of 45 kph. Do you think the Alphine 11 Di2 would work on my bike? I am so done with derailleurs.


    1. Hi Michael,

      It should be a fairly straightforward conversion. You’ll need to check the rear dropouts are traditional quick release, as I don’t believe Shimano have a thru-axle fitment yet. You will also need the Shimano Alfine chain tensioner.

      I hope this helps, let me know if you have any more questions.

      All the best,

  2. The question is …..can I ride a sturmey archer hub with 8-gears on my ebike with a Bosch performance, performance CX , ? Nothing to find about it !!

    1. Yes, the Sturmey Archer 8-speed hub will be fine to use with the Bosch CX. It’s a fairly robust unit and will cope with the extra torque.

  3. Hi Brian
    I like the practical advice you give on your site-it’s refreshing to read.*I have a Cannondale Topstone Lefty Neo Carbon 3 ebike. I ride a 37 mile route(it changes every once in a while) to achieve my avg heart rate goal. The routes are 100% pavement with a healthy dose of hills and flat riding. The low weight of the bike makes it easier than most ebikes to transport and was a key reason I went with it. I’ve been reading about internal gear hubs. I like the easier shifting and especially the low maintenance. Which internal hub would you recommend ?

    1. Hi Saul,

      I would go for the Rohloff Speedhub A12 version which is compatible with 142mm thru-axle. It’s expensive, but well worth the investment. They do an electronic shifting version as well. I’ve checked the Shimano website and they don’t currently offer their Alfine hub in thr-axle configuration.

      All the best,

  4. Peace…I have a Old Europa Ultra Motor that I like to rebuild with a mid drive . Any suggestions or help would be appreciated . Why middrive? The bike is a steel framed ebike making it heavy for hill climbing and I live in a hilly area , however its built strong like a tank …needs TLC .N

  5. i am cuirious if anyone is familar with the swiss bike having a archer 8 gear hub and rear hub motor combined into one unit it sure sounds like they got their motors crossed but who knows ?

    1. The bike you are referring to is the Stromer – the motor is made by Taiwanese company TDCM and incorporates a Sturmey Archer 5-speed internally geared hub. There’s more information and images at

  6. Hey Tony, thanks for this informative and encouraging article.

    I am the proud owner of a new Serial 1 MTN/BASH single-speed ebike and I love love love the Brose mid-drive, the Gates belt, the stellar brakes tires and bearings. Putting 30 miles a day on a single speed is awesome… but I have been daydreaming about adding a hub shifter.

    Would you recommend one of these for my setup? I have more research to do from your links, but the Shimano 8 seems the ticket… but the Sturmey looks the part of a retro inspired high tech hog. I love that polished case!

    Serial 1 has encouraged me to experiment but has not made any recommendations. I know at 90nM it will have to be a beefy one.

    1. Hi Brian,

      My personal choice would be the Shimano Alfine 8. This seems like a robust unit and should easily cope with the 90Nm from the Brose motor. About three years ago, I installed a couple of these on e-bike conversions using Bafang BBS02 750w mid-drive motors (120Nm of torque and over 1000w peak power). No long-term reliability issues were reported.

      I’ve only installed Sturmey Archer IGH on a couple of bikes with front hub motors, but I’ve heard the 3-speed version works particularly well with powerful mid-drive motors like the 1500w Bafang BBSHD.

      I hope this helps.

      All the best,
