For consumers who do have an EP8-equipped Commencal with e*thirteen cranks, the Andorran brand is offering to replace the e*thirteen cranks with Shimano ones, regardless of whether theyve experienced issues with their EP8 spindle or not. Also did some trail work. - Can we have remaining battery displayed as a percentage please? Pickup is faster too, with less hesitation between pedalling and torque being delivered to the rear tyre. Shimano advises that only approved crank arms should be used with its DU-EP8 drive units, reads Shimanos statement. I have a gen 3 and it's totally quiet when coasting . 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. That is, spme pretension or a clutch like system. That just isn't real world riding though, you just don't spend all your time in boost mode. 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. Some claim it's a dangerous motor that suffers spindle failures. With the new EP8, Shimano managed to close the gap to its biggest competitors. The Kiox head unit has a nice colour screen with plenty of useful data on it, but were not sold on the magnetic attachment and the fact that the motor wont turn on without the head unit. We recommend only Shimano cranks for usage with our drive units. 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. "- Only five power bars for charge level.". You can't call an e-bike rider lazy when they try to overtake you making this sound. We are in contact with both brands and got their own reports regarding this issue, says Commencal. In the lower settings, youll have to pedal really hard to get maximum support the motor. Here youll find three sliding scales for each of the three assist modes (thats Eco, Trail and Boost). 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. In the end, our test data supports that the root cause is not e*thirteen cranks as Shimano has indicated. Its the Orbea Rise that achieves the most discreet integration however, with a frame that was purpose-built around the smaller EP8 motor, rather than having been retrofitted from a previous E8000 drive unit. Hes one of BikeRadars lead testers and knows how to push bikes and products to the limit, searching out the equipment that represents the best value for money. If youre sprinting at speed, the Levo feels sticky and lazy in comparison to the drag-free EP8 motor. While some frames will resonate more than others, the noise is otherwise normal, and it doesnt take long before your brain subconsciously ignores it. I wish real bike reviews were this detailed. Shimano has put its long-running Steps E8000 format to pastor and heralds in its EP8 motor unit for 2021. 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. It is the most underrated comment ever on the pinkbike. 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. I chose this bike because it has the EP8 and from research, seems to be the most reliable platform out there, assuming it's as reliable as the E8000. With that said, all my riding is tough climbs and steep descents, without an e-bike would be walking up a bunch of it. There's 21-percent more torque (85 N/m total) in Trail and Boost modes. I thought ebikes were supposed to enable us to do more fun stuff in less time. The new motor, called EP8, is 10 percent smaller and is a lot lighter. 1. We will have them soon available in all our subsidiaries (Canada, USA, Chile, Australia, NZ and Reunion Island) to reach all our customers worldwide.. So, when the sensor senses a negative elevation gain, the dynamo kicks in to recharge the battery. Wait until you see how much work it takes to replace rear derailleur housing! So many issues that can be simply solved by not having a motor. Sign in to manage your newsletter preferences. I have tested a few ones and to me best one is Specialized in terms of ridding feeling and refinement. 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. You can hear the motor spinning and attempting to assist, but no power is delivered. On top of that, Shimano also appears to be cool with brands building their bikes with non-Shimano batteries. There are 5 levels of adjustment from Mild to Quick, with the highest setting requiring only a small rotation with light pedal force to engage the motor. Climbs really well and descends like a beast. I own the Levo SL, and it is the most refined ebike I have ridden so far. - High quality display & controller If a Commencal customer has been unfortunate enough to experience the EP8 spindle failure this article is discussing, the brand told us its warranty programme means Commencal would assume all responsibility for getting the customers bike running again. Just kidding! What would happen if a consumer noticed their axle was cracked in the way described on e*thirteens TSB? 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). This means its impossible to tell whether you have 21% or 49% battery remaining. -- Wild Bill. Its almost as if the battery drains faster in that final 20%. One note on range Shimanos range estimation is not reliable. 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. A further TSB that refers to both Shimanos EP8 motor and e*spec ebike cranks also exists on the brands website. 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. Basically, the battery level drops from around 30% to 2% extremely quickly. 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. He started racing downhill at the tender age of 11 before going on to compete across Europe. I find the author of this article is overly picky. Shimanos answers to our questions are published below verbatim. 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. 20ft into my ride and the motor cut out. Despite the musclier performance, weve had excellent results in terms of range, with the Bosch motor regularly achieving more miles and elevation over EP8. is a broken record . If you have a problem you can reapair it very quick. You still have the three basic assist modes: Eco, Trail and Boost. Posted Oct 21, 2020. The ability to customize the boost is very useful, with Shimano's app you can dial it in to your preferences. Truly unfortunate you lost it. According to e*thirteen, the safety inspection is relevant to all EP8 owners, regardless of what cranks are fitted. My first thoughts are that the disengagement part of the motor that allows it to pedal freely after 20 has already broken. Theres still a whirring noise from the metallic gears inside, and the pitch increases slightly at higher cadences. Great for climbing, on the descents the weight changes how I ride, not better or worse. Thanks! 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. What's left is just a plain old mountain bike with a weight around 14kg. Save 30% + G-Form Pro X3 Knee Pads when you subscribe to MBUK magazine. Its also a very quiet motor when pedalling. The sign of a true technical rider. According to the TSB, only Shimanos EP8 motor is affected. Also worth noting is that you can create two riding profiles, which you can alternate between via the menu and push-button on the display. Purchased an SC Bullit in march and I now have 520 miles on it. That rattling feeling comes from one way bearing. 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. From what I get from the article, what would actually bother me more is how it kicks in from a standstill or trackstand. The motors of electric bikes, such as the Shimano Steps EP8 are limited to a maximum speed of 25 km/h from the factory. Only the Levos belt-driven Brose drive unit beats EP8 in terms of motor noise. Uh oh, another one E-triggered. 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. That is not the case, but all cranks should be checked for proper tightness before riding, and initial installations procedures should be updated, reads TSB 156. The Pivot Shuttle, for example, employs a huge 726Wh battery made by a third party company called Darfon. One is a Haibike Fat-Tire with a Yamaha Drive, the second is an absolutely brilliant 40lb (including battery) DIODE from LaMere Cycles in the USA. 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. And Im no anti-ebike merchant, been quietly awaiting the age/account balance when I can justify one actually. - Lightweight and small form factor 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 cheapest Specialized Levo is the Expert model, which sells for just shy of $16K. Upon a little digging on the internet, it appears that this functionality is only on offer for Garmin users. 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. That kind of thing can destroy a company's reputation even if it's not something serious . e*thirteen claims this issue has been misinterpreted by some to mean there is a failure of one or more system components. I also have Commencal 2021 meta power sx. 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. Chuckle. An e-Mtb allows me to ride farther, and more often and smile from beginning to end, not just the downhill sections! Easy fix. In the article it is not considered that much of an issue as supposedly trackstands are less common on e-bikes, but if I'd get one (if ever) that would be just what I can imagine myself do. In comparison, the MasterMind TCU display on the new Specialized Levo offers a significantly more customisable and overall user-friendly experience. We hope Shimano will join us at that table soon.. 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. However the motor operation itself is fabulous, smooth, powerful, feels natural when you ride, you can cover ground like crazy in this thing. Can they make it swappable with a gear box? 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. "but since I have to hit the small button repeatedly when my battery charge becomes critical on some rides". Shimano also claims this issue is entirely isolated to non-Shimano cranks, stating it is aware of 49 reported cases of spindle failure. While midly annoying, it only takes a couple button presses to get back to get an 800% stabbing strength increase! 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. 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. Their heckler had complete battery failure, the ship date for a new one is close to the motor ship date. The sound is the same, the motor works but you just hear it spinning. No, not at all. So why has no one made a motorized gearbox yet? It was one of the most fun bikes to ride. Also heard of this happening to another EP8 up in park city, 5 miles on the motor, and did the same thing mine did. Thanks to lightweight magnesium components, Shimano has shaved off a cool 200g of weight making it one of the lightest electric bike motors on the market today. How many instances of this problem has Shimano encountered? e-bikes remove the only non-financial barrier for entry into a sport that historically required at least some small amount of fitness. @tomdesoals: Yeah, I get that now that bikes have become more silent anything new that makes noise can become annoying. Step 2 - Identify if preload caps have a pre-applied threadlocker patch and apply if necessary. When youre descending down the trail, the volume and resonance are amplified. After downloading the free E-Tube Project app, youll need to turn the bike on and pair it with your smartphone. Overall it is a very refined system though. 2b - If threadlock patch is present, move on to step 3. 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. 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. They deemed it a warranty and the motor has failed. Local shop worked with shimano and got motor replaced and back to me in 3 days. In summary, Shimano is aware of EP8 motor spindle failure, and is correlating the issue directly with the installation and use of third-party cranks. 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. Nothing like on an ebike. Subscribe to Cycling Plus from just 13.50 and get a Lezyne Pocket Drive Pump, worth 29! 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. Just imagine if i had bought a Shitmano Ebike. "Unquestionably, Shimano has the cleanest and sleekest display integration on the market". 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. What makes me sad is seeing young people hop on the e bike train so that they can go on a longer ride or so that someone who is new to cycling can keep up with their friends who have been riding for years, all to perpetuate needless consumerism and a gross waste of resources. No mention on the worldwide recall of the motor due to issues? I've had a go on ebikes and think they're fantastic and good fun. Now I have $10k garage ornament that I can't ride for 3 months. Lapierre e-zesty. Furthermore, the range estimation is more accurate in our experience too. It is a feature bro, the sound of pure class. 2. I can only hear any motor rattling when I am doing really gnarly rocky downhill. Are we ignoring the fact that motor has been recalled/reworked by Shimano, and pushing all new bike deliveries by two months (at least)? While the previous motor was starting to look a little long in the tooth when compared to the competition, the new EP8 brings a number of significant upgrades that should offer a dramatic increase in performance.
