Which electric mountain bike motor is best is a question we get asked regularly at BikeRadar. Of course, the answer isn’t clear cut, but Alex sheds light on where each motor, from the four main manufacturers, performs best and where they falter.

First is Shimano’s EP8, officially the DU-EP800, fitted to a host of bikes including Santa Cruz, Yeti, Marin, YT Industries, and Nukeproof.

Next is Bosch’s Performance Line CX fitted, among others, to bikes from Mondraker, Trek, Whyte and Scott.

Then there’s Brose’s Drive S Mag, also known as Specialized’s Turbo Full Power System 2.2 Motor. This system is fitted to Specialaized’s most powerful ebikes, and models from German brand Rotwild and Spanish brand BH Bikes.

Finally we’ve got the Giant and Yamaha developed SyncDrive Pro, also known as the PW-X3. Most famously fitted to Giant bikes, it’s also available on some Haibike and Raymon models. This isn’t an exhaustive list of ebike motors, however.

Fazua’s Evation – a modular lightweight, lower power motor – fitted to bikes from Kinesis and Lapierre, goes head-to-head with Specialized’s SL Mahle-made lightweight motor on their Turbo Kenevo SL and Turbo Levo SL bikes.

Canadian brand Rocky Mountain’s ebikes are fitted with a full-fat motor called the Dyname drive system, and is only exclusively available on Rocky bikes.

Panasonic also makes motors, and there’s Shimano’s de-tuned EP8 RS found on the Orbea Rise to consider. There are a host of rear hub motors, too, but these are less relevant for mountain bikes.

To avoid over complication, We’ve decided to compare the four most common motors you’re most likely to encounter when considering an ebike purchase.
