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). I mean, one of the most beautiful things about the bicycle is how efficient and capable it is of traveling long distances under our own power. On one ride with the Canyon Spectral:ON, the range estimation initially showed 25km. Those Merida ebikes ride quite good too. It also depends on the bike too. Maybe it's specific to the commencal frame design transmitting sounds? A forum community dedicated to Mountain Bike owners and enthusiasts. Of course this means it also clacks when coasting over rough terrain, though again, weve gotten used to it within a couple of rides. The ability to customize the boost is very useful, with Shimano's app you can dial it in to your preferences. The Shimano EP8 RS of the Orbea Rise does not present physical differences concerning the EP8 that we can see mounted on other e-mtb's. Its dimensions and weight are the same. 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). Its clear why this motor is becoming popular with so many bike brands, given the flexibility it offers frame designers, particularly with the variety of battery options on offer. And we certainly wouldnt be upset if Shimano could quieten down the clacking noise. However, we couldnt get the display to pair with our Wahoo ELMNT Roam head unit. Maximum Torque This allows you to limit the maximum torque, with 10 levels of adjustment from 20 Nm to 85 Nm. I swapped wheels but didn't realize I had to swap the magnet from the rotor bolts that was connected to the speed sensor in the software. A downside of the 2.2 motor is that it is noticeably draggy above the 25km/h cutoff though something we experienced during back-to-back between the Levo and Canyon Spectral:ON. Theres still a whirring noise from the metallic gears inside, and the pitch increases slightly at higher cadences. 5Nm doesnt sound like much on paper, but on the trail the Levos 2.2 motor is noticeably musclier than Shimano EP8, particularly at the extreme ends of the cadence spectrum. However, where the Bosch Gen 4 feels like a diesel engine at low RPMs, the sporty EP8 drive unit still prefers spinning at a higher cadence. Durability and ease of maintenence is far more important than power in my world.

Yeah but who needs all that power? 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. In comparison, you can get a Polygon Mt Bromo N8 with a Shimano EP8 motor for $7,899 AUD. - Numerous battery options, both from Shimano & 3rd parties It isnt a huge difference, but sometimes its just enough for your rear wheel to make it up and over a stubborn tree root or rock ledge. 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. In fact, we found ourselves tuning it out completely a couple of rides later. As it stands, you have to use the small button at the base of the display to manually scroll through additional pages just to see your cadence, estimated range and the time. The clicking sound has no effect on the function or durability of the drive unit. It's kinda frustrating. 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. It is the most underrated comment ever on the pinkbike. A kilometre later that estimation dropped to 14km, then not long after to 9km, then to 5km, before the motor automatically switched into emergency limp home mode. This, of course, is good news for Commencal customers with EP8 drive units and e*thirteen cranks, and were hopeful other brands will follow suit. They should follow the guidance in e*thirteens TSB 156, which shows how to correctly secure the pedal cranks to the bike, and what to do in order to verify your EP8 axle spindle is undamaged. I've spent some time on this motor and it's one of the first to feel organic in the way it adjusts to the rider's pedaling. Our advice is not to rely on the range estimation in the first place. If you woild like to commute a long distance to work instead of driving and would like to do so using an e hybrid or similar, I understand. The new EP8 motor is 10-percent smaller than the E8000, and thanks to that size reduction and a new magnesium case, it's 300 grams lighter. The MasterMind TCU head unit on the top tube is also as good as it gets, with a sharp and clear, but unobtrusive display that reduces clutter on the handlebars. 2. 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. 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! So far so good. As well as being smaller, lighter and more efficient, the new EP8 drive unit also packs more punch with up to 85Nm of torque, bringing it up to speed with the latest power plants from Bosch, Yamaha and Brose/Specialized. Both bikes were fitted with e*thirteen cranks. I find the author of this article is overly picky. Power delivery is immediately intuitive thanks to the new MasterMind firmware that Specialized developed specifically for the 2.2 motor, which reduces power spikes from rapid changes in crank speed and pedal pressure. Yeah, that's pretty poor! 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. We have shared the results with Shimano and select OEM customers. We will have them soon available in all our subsidiaries (Canada, USA, Chile, Australia, NZ and Reunion Island) to reach all our customers worldwide.. If youve experienced a Shimano EP8 bottom bracket spindle failure, let us know in the comments below. Shimano also claims this issue is entirely isolated to non-Shimano cranks, stating it is aware of 49 reported cases of spindle failure. - Tuning options are simple and effective Couldn't agree more. Can someone make a bike with 50% - 100% assist? Not everyone has the time to grind for an hour up the climb. Shimano doesnt state what those design differences are, however. All e-Bike assist mode gets disabled during the downhill slopes. We bought drive units and crank arms, we are replacing at our cost all damaged parts and are covering labor [and] shipping costs that might occur. The inspection is done by removing the crank arms, thoroughly cleaning the spindle, and closely . For commercial info: [email protected]. 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. The most prominent reports of EP8 axle failure exist on two EMTB forum threads. Certainly of all the full-power motors weve tested, Shimano EP8 affords the most seamless feel as the power fades in and out around the assistance cutoff. This is part of our COMMENCAL Care program, we consider a warranty case should have no cost at all for any of our customers.. There are 10 levels of adjustment, from Eco to Powerful. I think Shimano is taking these issues very seriously. 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 allows bike companies to engineer a single frame, while offering cheaper models with a 504Wh battery, and high-end models with a 630Wh battery. The EM800 display features built-in Bluetooth and ANT+ wireless connectivity for pairing both your phone and a compatible GPS head unit, allowing you to display information such as battery life and remaining range. I'd do way more on a big day. It doesn't feel good. Im the worlds biggest ebike fan & I quite agree. Funny that Shimano now budget e-bike motor builds? If you aren't climbing steeps and requiring the torque, you would get way longer distance. If there is no threadlocker patch, move onto point 2c. As mentioned above, the Assistance Character bears the biggest influence on the motors on-trail feel, and dialling this down can make quite a big difference to the amount of range you can get from the battery. To replicate field failures, we had to look outside of the required ISO and EN testing requirements as those tests were passed successfully. Their heckler had complete battery failure, the ship date for a new one is close to the motor ship date. Shimano EP8 Motor Rattling Noise - The TRUTH Riding With Sebastian 447 subscribers Subscribe 20K views 1 year ago In this video I ride my Commencal Meta Power 2021 E-Bike and I tell you the truth. Approved crank arms are listed at si.shimano.com and are communicated towards bicycle manufacturers. there are no additional ports on the SC-E5003 to connect the switch with. The Good, the Bad, and the Ugly: The Real Bike Weights from PB Editors. is a broken record . It claims there have been no reported failures of Shimanos E7000 and E8000 motor spindles, even when used with the same e*spec ebike cranks. This means that if you ride in the default Trail and Boost settings, youll actually end up with a similar total range as the old E8000 motor, albeit with the benefit of more power and assistance throughout the ride. I tried to find out the cause of this. It is MUCH less powerful, but there is no rattle, no weird cut off, no jerky pedal action. It's like a dirt bike with a 15 mile range. There are no reported cases of spindle breakage of DU-EP800 when assembled with Shimanos cranks. While the EP8s performance on the climbs is generally excellent, we have occasionally wished for a little more overrun for clearing technical features. First revealed to the world in September of last year, Shimano EP8 finally arrived on the e-MTB scene as the successor to the very popular Shimano E8000 motor. Its considerably bulkier than Shimano EP8, dominating the Levos frame profile while also putting limitations on rear wheel clearance. Sources at numerous ebike suppliers have told Cycle Volta this week that releases of new EP8-equipped electric mountain bikes are being held up, on Shimano's direction. Shimano tried to take the Apple approach to antennaegateyou're holding your phone wrongyou're coasting your bike wrong. I like to see a dynamo recharging system when the bike starts to coast downhill. I do not have a car. I've already posted this on the Commencal Meta SX Power thread, but wondered if other bikes with the Shimano EP8 motor and battery have seen a similar problem. It also responds a fraction quicker at the pedals, and delivers more overrun power when ratcheting the pedals over technical features up a climb. We recommend only Shimano cranks for usage with our drive units. Also a big improvement over the prior motor is that the EP8 freewheels easily, so on flats or downhill you can blast away without motor resistance. The YT Decoy also utilises its own 520Wh battery and the the Orbea Rise is built around a smaller 360Wh battery. The EP8s smooth power delivery is mirrored by its exceptionally low drag something that is totally noticeable (or rathernot noticeable) around the 25km/h cutoff point. As expected, the new Shimano EP8 motor gets a hefty boost in power, with a claimed maximum torque output of 85 Nm. Damn, sorry to hear this especially since I own the same bike! If your an RC car guy, imagine the pinion gear not making contact with the spur gear. Please, It appears you're using an old version of Internet Explorer which is, the 471.5mm rear centre on the Giant Trance X E+, that achieves the most discreet integration, the MasterMind TCU display on the new Specialized Levo. And more power requires more juice. 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. If thats the case for you, start at Level 5 and work your way down a notch at a time. While some frames will resonate more than others, the noise is otherwise normal, and it doesnt take long before your brain subconsciously ignores it. Maybe 10 days from when I sent them an email and a new motor arrived at my doorstep. Sell it to me, bet ya cant specially at a respectable 90 keys. Really? I also got it second hand as I just can't afford new. Too hot to handle even. The new EP8 drive unit provides incredibly quiet assistance under pedal load. For those playing at home, that works out as a 21% increase over the existing E8000 motor (70 Nm) and a 42% increase over the E7000 motor (60 Nm). With 21% greater torque than E8000, the EP8 motor delivers substantially more punch on the trail, and it feels more usable too. If you don't like e-bikes for whatever reason, you really have no business even commenting on this review. I suppose pedal assist allows you to tackle the more fun/steep/tech climbs but to be effective it needs to be subtle too. And you're clearly not pedaling, just pure flow. When the motor applies torque it pushes in one direction and closes the gap, when there is no torque the ring can rock a little. - Lightweight and small form factor I've never heard the rattling noise that has been posted in the early reviews - the motor is super quiet, so it looks to me like much ado about nothing. Click on a component to learn more. However, you do pay for all that refinement and integration. 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. Also did some trail work. As to how the de-tuned EP8 motor performs? Probably more than some rattle. 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. Another bike that features Shimano EP8 is the new Orbea Rise. Lapierre e-zesty. Make it 100 mile range, and I'm in. 2023 Thok TK01 R Review | A surprising package from an Italian e-MTB specialist, 2022 Canyon Spectral:ON Review | A better e-MTB in almost every way, 2023 Trek Fuel EXe Review | This brand new lightweight e-MTB is the stealthiest weve ever tested, Rocky Mountain Altitude Powerplay Review | Power is nothing without control, This website requires Javascript for optimum viewing purposes. Wed much rather see battery life displayed as a percentage, and the option to customise the screen. [The] topic has been closed from Shimano[s] side but e*thirteen is still investigating with independent labs.. This is particularly noticeable on traction-poor climbs, even when starting from a standstill. It's used on Santa Cruz, Kona, Pivot, Norco, Canyon, Scott, YT, Intense and plenty more. Weve noticed this while pedalling along forest double tracks and on the road to and from the trailhead, but its also apparent when sprinting along faster sections of singletrack. There's 21-percent more torque (85 N/m total) in Trail and Boost modes. e*thirteens analysis suggests that some Shimano EP8 spindles may have manufacturing defects which, over time, can develop into cracks with use and exposure to the elements, reads TSB 157. Are we ignoring the fact that motor has been recalled/reworked by Shimano, and pushing all new bike deliveries by two months (at least)? Yesterday I drove down south to explore some new trail in Utah. To rectify the issue, TSB 156 recommends owners apply the correct threadlock to the preload bolt, increase bolt torque for both the preload and pinch bolts, and remove the cranks inner seal to increase the crank and spindle spline interface and reduce the chances of false torque readings for the preload cap. 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. @tomdesoals: Ah, thanks I get it. I also have a YT Decoy with Shimano E8000 motor. 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. Do you think it could be only an issue with Carbon frames then? One note on range Shimanos range estimation is not reliable. Along with the new EP8 motor, Shimano has also released a larger 630Wh battery, which seems to be the most popular option at the moment youll find it inside both the Canyon Spectral:ON and Merida eOne-Sixty. The version I've been riding on was 17,8kg. What's left is just a plain old mountain bike with a weight around 14kg. Appreciate the level of detail in this article, good work. So when the new version is so much better Refinement is all relative. The brand told us it was aware of the spindle issue and has been in contact with both Shimano and e*thirteen about it. The three EP8 bikes weve tested all have sub-440mm rear centre lengths, which is quite a bit shorter than the 471.5mm rear centre on the Giant Trance X E+ with its much bulkier Yamaha motor, for example. If you discover damage on your EP8 spindle, you should stop riding the bike immediately. Stab happy!". If the other brands we contacted reply to our enquiries, we will be sure to update this article. Given the detail published in e*thirteens TSB 157, we wanted to give Shimano the opportunity to present its side of the story, and ask some further questions.
