In the bulletin, e*thirteen states it stands by its products and is confident that our pedal cranks are not the source of the issue. SpecializEd # levo SL is a great benchmark Have had a Specialized Levo & sold it due to making weird noises, so yes other manufacturers have problems too, not saying that is easy to get good reliability with new technology, but my Shimano e-8000 motor has been more reliable even is very wet weather! Its worth noting that Bosch motor is only compatible with Bosch battery options though. Under this condition, with each ride the crack can expand, and this can result in a spindle breakage.. It's a similar level of feeling to Gen. The Pivot Shuttle, for example, employs a huge 726Wh battery made by a third party company called Darfon.

Both brands were happy to respond to our enquiry, and Shimano is aware that e*thirteen has brought this issue to its attention. Can we get reviews this in depth for regular bikes? - Range estimation is not reliable. For a lighter pedal feel than the E8000, the one-way bearing has reduced its rotational resistance, creating a free play. What this article says to me is no wonder people make fun of mountain bikers. But please don't anyone kid themselves that it's as much of a work out as an analogue bike, if there was no mechanical advantage over analogue what would be the benefit. Our drive units are not tested for use with third party crank arms.. Currently, I own two e-bikes with a new 2022 Moustache Samedi 26 Fat 4 with the Bosch Motor on its way. Sometimes that means a DIY fix and other times it can mean a recall, software update or part replacement by a dealer.

Specialized is close to this. me-bikes: Ibis Exie, Ibis Ripley V4, Ibis Ripmo V2. When we make fun of others, its because we are not happy w ourselves. I have a gen 3 and it's totally quiet when coasting .

Furthermore, having the battery life displayed as five bars is positively rudimentary. Already have an account with us? Hey Ralf Hauser!! A dinamo or recharging when braking or something That's what I'm still waiting for! If you aren't climbing steeps and requiring the torque, you would get way longer distance. On top of that, Shimano also appears to be cool with brands building their bikes with non-Shimano batteries. The Brose Mag S motor has been used in the Specialized Levo and Kenevo since 2018, though it was recently updated for the release of the new Levo. The charge bars are a major issues though on the 8000, after a bit of use the battery becomes extremely unpredictable. Limiting the maximum torque is something youll notice more at low cadences in high-load applications rather than general trail riding. If in doubt about such components, we recommend speaking to your bicycle manufacturer.. The lowest setting sees the motor responding slower to your pedalling inputs.

Yesterday I drove down south to explore some new trail in Utah. This occurs if the cap is not correctly tightened or the factory-fitted threadlock hasnt been adequately applied, and if the crank arms pinch bolts arent tightened to their correct torque. If there is no threadlocker patch, move onto point 2c. I've had a go on ebikes and think they're fantastic and good fun. Now well point out here that the Bosch Gen 4 motor exhibits a similar metallic clacking noise, since its internal gear system also employs a clutch.

Put on i9 Hydra hubs, annoying motor rattle sounds disappears. The investigation has led e*thirteen to produce technical service bulletin 157 (TSB), published on its website on 14 October 2021. Its easy to modulate via how much pressure youre putting through the cranks and the power delivery is progressive, giving it a very natural feel as a result.

I think Shimano is taking these issues very seriously. Also did some trail work. It's significantly more muscle, which was much-needed in order for Shimano to keep . Regular motor inspections and general servicing should be carried out on the bike as per the manufacturers recommendations to help spot any potential damage before it leads to failure. 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. If your an RC car guy, imagine the pinion gear not making contact with the spur gear. The thing is though, you do actually get used to that noise. Maximum power output sits at 500W, although the. My local rides average 30-35km with just under 1km of climb. An e-Mtb allows me to ride farther, and more often and smile from beginning to end, not just the downhill sections! "but since I have to hit the small button repeatedly when my battery charge becomes critical on some rides". 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. You are not alone. While I am at the age/account to have one, I couldn't imagine riding longer than my 630W battery lasted, i don't think i would be able to walk for a week. Have had my Norco Range LVT with the EP8 for a week and have noticed the noise, maybe once? only one port which needs to be connected directly to the motor.

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? It even surpasses them in terms of noise (very quiet under load) and weight. The sign of a true technical rider.

Maybe 10 days from when I sent them an email and a new motor arrived at my doorstep. And just read any car review of the blend between regenerative braking and hydraulic, then decide whether you want a computer deciding to regen as you roll off a drop regen braking is pretty much impossible on an ebike as it requires the use of a direct drive motor. While the EP8s performance on the climbs is generally excellent, we have occasionally wished for a little more overrun for clearing technical features. If you have a problem you can reapair it very quick. Seems quite useful for when pushing the bike up these impossible climbs. The Shimano EP8 user interface is similarly elegant in its design. I do not have a car. That rattling feeling comes from one way bearing. I would have respected Shimano more if they owned it and were more forthright about working to resolve it. Quick everyone, it's another article about e-bikes grab the pitchforks! That kind of thing can destroy a company's reputation even if it's not something serious . Its mostly apparent when freewheeling down really rough trails, but weve been able to detect it when the motor is engaging and disengaging around the 25km/h cutoff on the road, and while cruising over washboard bumps on mundane fireroads. What can consumers expect to happen if their EP8s spindle fails? What would happen if a consumer noticed their axle was cracked in the way described on e*thirteens TSB? A dynamo and regenerative braking is the ONLY thing stopping from buying an e-bike? But on the premise of further, faster, more fun, that range at full noise is not gonna outdo the range & fun I get outta my bowl of cereal and some old fashion pedal power. I have no personal experience riding with pedal assist but when I hear the high whiz from the motor I think that would drive me mad too. Indeed Specialized actually built the new Levo around a mullet setup with a 27.5in rear wheel, in order to shorten the chainstays. I'm not an ebike hater - but (you knew it was coming) - I can't ever see myself being able to justify the expense of one and I wouldn't like to risk a second hand one. Lapierre e-zesty.

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. According to Shimano, the EP8 motor offers a 36% reduction in drag over the old E8000 motor, and were inclined to believe that claim. So then it gets really confusing as it seems like the first bar lasts 30% and the last one 10%. The new EP8 drive unit provides incredibly quiet assistance under pedal load. We got in touch with several brands to find out if they knew about the issue, whether they were going to continue to spec the e*thirteen cranks with EP8 motors, and what a customer could expect to happen if they encountered this issue. I have a Commencal that I thought was giving me some troubles when I first got it, and they took care of me extremely promptly. Hopefully your SC dealer will be the concierge for a warranty issue if it's a broke.

In addition to those weve tested, youll be able to find Shimano EP8 on the Santa Cruz Bullit & Heckler, Marin Alpine Trail E2, the Commencal Meta Power, YT Decoy,Pivot Shuttle and Mondraker Dusk. My take away besides the obviously pro/con talking points was the weight of the bike. 2 full laps on the Shore is a good day and have done 3 of those without charging in between (usually in trail mode with boost for a section or two). Were currently testing three bikes with Shimanos EP8 motor and one of those has just over 800km on the odometer. 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. It is MUCH less powerful, but there is no rattle, no weird cut off, no jerky pedal action. 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. In the lower settings, youll have to pedal really hard to get maximum support the motor. Regardless ebike or "normal" MTB. 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. Aim for a cadence between 70-90 RPM for maximum efficiency and response from the motor. Purchased an SC Bullit in march and I now have 520 miles on it. The actual mechanism works well but is very easy to break, just turn the allen key the wrong way by mistake..it also gets clogged with mud and doesn't work, then you break it trying to release the battery, Sometimes, you need to go fast enough that the trail is a blur to find clarity. For the type of riding and trails I do, battery power is not an issue, in fact would look at a smaller battery and weight savings on my next rig. But to give you some numbers, weve consistently achieved around 1,500m of climbing during our 30-50km test rides. Environmentally I think they're a disaster as well - rare earth elements in the batteries for one thing. Anyone having problems with the charger? We asked Shimano and e*thirteen for comment on the spindle cracking issue. The new motor, called EP8, is 10 percent smaller and is a lot lighter. The Purion controller is vastly simpler and easy to read, but it looks cheap and its bulky, making it an awkward fit with brake and dropper levers. The version I've been riding on was 17,8kg. If consumers use the recommended cranks, there should not be any issue this combination meets our strict and exacting quality standards. 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. Overall the tuning adjustments are quite noticeable, though wed always recommend only adjusting one parameter at a time to isolate its effect on the trail. Shimano says it provides up to 350-percent support (in Boost mode versus the E8000's 300 percent). If youve experienced a Shimano EP8 bottom bracket spindle failure, let us know in the comments below. This will be a far more accurate method for determining your estimated range. All I could find is that bike manufacturers are to hold off selling the EP8 until Oct/Nov while they addresses some final issues. The YT Decoy also utilises its own 520Wh battery and the the Orbea Rise is built around a smaller 360Wh battery. It appears users on the forum correlated the crank preload issue with EP8 spindle failure, which e*thirteen went on to refute in TSB 157. Durability and ease of maintenence is far more important than power in my world. Occasionally it can feel a little peakier compared to EP8, but for the most part both motors are easy to get used to within a few rides. Climbs really well and descends like a beast. All you guys "waiting" to get a ebike are blowing it..the bikes are refined trek rail no problems..going around the country slaying every trail I see chugging beer and laughing at all u haters.. believe me I guys will all be on one sooner than later.

This also allows brands to more neatly integrate the motor into their frame designs, Canyon having done a particularly swell job with the Spectral:ON. Once again still want to know; is the BB replaceable on these units yet, or are they still landfill waiting to happen? An E-bike with 200 watt power assist, 350 WH battery, and total weight of bike under 34 lbs. Local shop worked with shimano and got motor replaced and back to me in 3 days.
