As of April 2021, all of Commencals EP8-equipped bikes have been specced with Shimano cranks, but this change has taken some time to filter through to consumers because of the time it takes for fully built bikes to get to the shop floor. With 21% greater torque than E8000, the EP8 motor delivers substantially more punch on the trail, and it feels more usable too. Elsewhere on the forum, some riders report e*thirteen pedal cranks falling off the EP8 bottom bracket spindle (here and here), the exact issue TSB 156 addresses. Those Merida ebikes ride quite good too. Here youll find three sliding scales for each of the three assist modes (thats Eco, Trail and Boost).

According to Shimano, the EP8 motor offers a 36% reduction in drag over the old E8000 motor, and we're inclined to believe that claim. This is particularly noticeable on traction-poor climbs, even when starting from a standstill. The compact size and a magnesium casing helped cut 300 grams. Don't all e-bikes feature walk assist? Our advice is not to rely on the range estimation in the first place. Why so delicate, bro? You miss that obscure offering from Specialized? With the Spectral:ON for example, which has very short chainstays and a relatively slack seat tube angle that puts your weight further over the rear axle on steep climbs, it helped to dial down the Assistance Character (to 6/10), the Maximum Torque (to 78Nm) and the Assistance Start (to 4/5) to soften the bikes power and acceleration.

Ebikes are great as a self shuttle, especially for time limited people. I have the EP8 on a Commencal Meta Power. Weve found the first two settings to be too weak for e-MTB use, though conversely the highest setting can feel a little too peaky for some riders. The updated Trail mode is brilliant, and the option to fine-tune each assist mode is a welcome feature for achieving the desired feel while maximising range.

Indeed Specialized actually built the new Levo around a mullet setup with a 27.5in rear wheel, in order to shorten the chainstays. I can only hear any motor rattling when I am doing really gnarly rocky downhill. Thus, I could ride a few feet with power then the motor would cut off.

However, you do pay for all that refinement and integration. me-bikes: Ibis Exie, Ibis Ripley V4, Ibis Ripmo V2.

This is a real review with details and pros and cons. If you don't like e-bikes for whatever reason, you really have no business even commenting on this review. Its a little different though, with Orbea detuning the motors power and assistance to improve efficiency so it can use a smaller and lighter 360Wh battery. As to how the de-tuned EP8 motor performs? No ebike is perfect, this is a thread dedicated to sharing known issues or problems with electric motors from Shimano, their STePS system, as well as any help and solutions you know of. Display integration is still the best on the market, even if it only shows five bars of battery level and could easily integrate some more user-friendly features. Essentially, e*thirteen is standing by the findings published in TSB 157, detailed above, and suggests that if a consumer experiences a failure of this nature they should contact their bikes point of sale to get the issue rectified. You also need a special key to release the battery from the frame, which were not fans of, at least for a mountain bike anyway.
