Simply enjoy what you are riding and watch the world, I should say, e-bike world, pass you by, as they are here to stay and while they are not perfect they are probably the best and most exciting thing to happen to the bike industry in 50 years! The cause is due to the difference in design from Shimanos crank, which causes increased stress around the spindle hole.. The svelte motor casing provides more clearance for the rear wheel and suspension components, allowing brands to build their bikes with shorter chainstays. Are we ignoring the fact that motor has been recalled/reworked by Shimano, and pushing all new bike deliveries by two months (at least)?

Wait, 23-27kms? Not a big Chan e but worth a look. This BT-8036 battery only needs a 4mm hex key to be released from the frame for charging separately, which is unlike Bosch that requires a special key (potentially something else to lose/forget). Meanwhile, e*thirteens response places the ball firmly in Shimanos court. When we see failures like this, it is incumbent on us to find the root cause and, if it is within our control, provide a resolution, reads e*thirteens statement. While weve certainly been impressed by the power, ride feel and tuneability of the Shimano EP8 system, how does it stack up against the likes of Bosch and Brose/Specialized? Great for climbing, on the descents the weight changes how I ride, not better or worse. Along with the svelte carbon frame, that helps to reduce the total bike weight to as low as 16.2kg, creating a potentially worthy adversary to the Specialized Levo SL.

Weve ridden the latest Bosch Performance CX Gen 4 motor on a variety of e-MTBs, including the Cube Stereo Hybrid 160 and the Trek Rail. How stuff like this gets through what I would like to think was extensive testing I will never know. I have to admit some of the comments make me laugh out loud while others score some points for being helpful and based on fact, not hearsay fiction. 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. So this one article, about this one e-bike, says to you that ALL e-bikes lack refinement and therefore aren't worthy of you gracing them with your holy ass?

On top of that, you cant tune the Bosch motor like you can with EP8 theres no fancy app, and the stock assist settings arent adjustable what you see is what you get. 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. - Strong but very well-tuned power delivery I like to see a dynamo recharging system when the bike starts to coast downhill. If consumers use the recommended cranks, there should not be any issue this combination meets our strict and exacting quality standards. Oh man, so that must mean you know of rigs they've received that they've not done first rides and then field tests on. There's 21-percent more torque (85 N/m total) in Trail and Boost modes. it's been quite awhile and still no fix . Did some rides on a scott e-genius 920(2020) and my biggest one I did was a 115 km with 2000 meters of ascent ,19 km average speed,all in the eco mode and riding some rocky terrain with some tarmac ,fire roads ,very mixed terrain ,and I did got impressed with the power and the range ,didnt got me so tired on the legs its most a cardio ,but dont put more power on them and no more battery capacity,cause it wil make them almost a dirt bike :-((. It's kinda frustrating. quieter(+) smaller(+) lighter(+) more power(-) battery range(=). Generally on bikes we spend so little time braking that regeneration would be a waste of effort. 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. Stay tuned, as well have an Orbea Rise test bike arriving very soon. For riders scoping out bigger rides than that, youll want to consider dialling down the Assistance Character to improve efficiency.

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. Yeah, that's pretty poor! In the higher settings, the motor will deliver maximum power without you having to pedal very hard at all. Their heckler had complete battery failure, the ship date for a new one is close to the motor ship date. The question of what happens with this combination is for the manufacturer of that combination to answer.. I would have respected Shimano more if they owned it and were more forthright about working to resolve it. So then it gets really confusing as it seems like the first bar lasts 30% and the last one 10%. Those Merida ebikes ride quite good too. Side-by-side, the EP8 motor is slimmer around the belly and so offers a skerrick more ground clearance. But it is not anywhere near the same engine in everything else. On my older gen Bosch motor with a 500wh battery I can get about 30 miles out of a battery charge if I only turbo up the steepest climbs and do the other bits in low/mid power settings (and I'm about 100kg's / 16 stone which sucks battery).

Funny that motor has a gear box, but only one gear? Why so delicate, bro? This speed may be enough, but some people may find it very frustrating because from 25 km/h they have to make a gigantic effort to follow their teammates since the assistance is cut off or simply because they want to go faster. This gives a very wide and flexible power band that does well to match what your legs are doing, making this the go-to, set-and-forget mode for proper off-roading. Didn't think I'd ever see that.

This is because the assistance drops off quite quickly when you stop pedalling, particularly compared to the Bosch motor, which continues to push on for just a fraction longer. He started racing downhill at the tender age of 11 before going on to compete across Europe. Limiting the maximum torque is something youll notice more at low cadences in high-load applications rather than general trail riding. And that's with the big heavy battery too. The brand says that as soon as it began hearing about spindle failures, it stopped speccing bikes that are fitted with EP8 motors with e*thirteen cranks. The Bosch motor produces the same 85Nm peak torque output as Shimano EP8, and it offers a similarly drag-free ride quality beyond the 25km/h cutoff due to the motor decoupling from the cranks. When new the last bar of charge corresponds to roughly 15-20% charge, but over time this becomes 5-10%. While the increased power certainly grabs most of the headlines, we reckon its the compact form of the Shimano EP8 drive unit that offers the greatest advantage over its competitors. Can someone make a bike with 50% - 100% assist? That rattle would drive me bonkers. The fact that the EP8 motor uses the same mounting points as the old E8000 motor means there are a few bikes out there that were anticipating will be updated with the new motor like the Norco Sight VLT and Range VLT.
