Pickup is faster too, with less hesitation between pedalling and torque being delivered to the rear tyre. e*thirteen cranks are commonly specced on electric mountain bikes fitted with Shimano EP8 motors, by bike brands including Commencal, Marin, Orange and Orbea, among others. e-bikes remove the only non-financial barrier for entry into a sport that historically required at least some small amount of fitness. So that would include rocks, hops, trackstands but also sudden boosts from a standstill. me-bikes: Ibis Exie, Ibis Ripley V4, Ibis Ripmo V2. Was thinking the same thing. It's a similar level of feeling to Gen. The investigation has led e*thirteen to produce technical service bulletin 157 (TSB), published on its website on 14 October 2021. Just kidding! 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. All bikes [have been] assembled with Shimano cranks since 2021 April.. Take note of how much elevation you achieve during those rides (elevation is more important than distance when determining range), and keep that number in mind when youre planning future all-day epics. This is part of our COMMENCAL Care program, we consider a warranty case should have no cost at all for any of our customers..

What's left is just a plain old mountain bike with a weight around 14kg. Good thing with Shimano is warranty,at least here in Madrid is almost instantaneous. If a dynamo can be worked into the wheel hubs, you may even get near perpetual charging while the system is in use. The issue, we've been told, is that the motor body is subject to cracking when the drive is employed as a stressed part of the bike's frame. Sometimes that means a DIY fix and other times it can mean a recall, software update or part replacement by a dealer. I haven't had the privelage to ride any bosch equiped bikes or other shimano bikes but this thing is so quiet I think it would be hard to find another ebike motor that is more silent. I suppose pedal assist allows you to tackle the more fun/steep/tech climbs but to be effective it needs to be subtle too. Stay tuned, as well have an Orbea Rise test bike arriving very soon. Shimano's EP8, short for DU-EP800, features a higher maximum torque of 85Nm compared to the older E8000's 70Nm, topping it by an extra 21%.

Shimano said August was the best. Can we get reviews this in depth for regular bikes? Its almost as if the battery drains faster in that final 20%. There are a lot of factors that influence range including rider weight, tyre choice, trail conditions, and elevation. Those Merida ebikes ride quite good too. And we certainly wouldnt be upset if Shimano could quieten down the clacking noise. And with brands such as Merida and Canyon making use of internal wiring through the handlebars, the whole arrangement is quite tidy. And in terms of backup service and support, the fact that there are far more Shimano dealers than there are Specialized dealers may also be preferable for some riders.

You can improve efficiency by limiting the maximum torque, though it is still possible to get maximum power out of the motor by pedalling at a higher cadence, so you wont necessarily get more range by limiting torque. Limiting the maximum torque is something youll notice more at low cadences in high-load applications rather than general trail riding. Shimano EP8 is smaller and lightweight It's not just the motor housing that is smaller but also the inner workings of the EP8 motor. At my age 69, if it isn't fun, exciting, and challenging, count me out! In the higher settings, the motor will deliver maximum power without you having to pedal very hard at all.

It even surpasses them in terms of noise (very quiet under load) and weight. There are 10 levels of adjustment, from Eco to Powerful. At full charge in Trail mode it says range is 90km or so but I haven't put that to the test on more mellow trail days but am sure others have. There is zero stickiness at the pedals that we could detect. My local rides average 30-35km with just under 1km of climb. Why don't they buy dirtbikes instead ?
