The YT Decoy also utilises its own 520Wh battery and the the Orbea Rise is built around a smaller 360Wh battery. Motor: Shimano EP8; Battery Size(s): 900Wh or 720Wh (M-XL), 720Wh on Small; They could have gone "yeah the rattling sucks but we hope you appreciate the motor nonetheless" but instead they composed this pure poetry. Make it 100 mile range, and I'm in. Still built around a block with 250W power outage under 36V, the maximum torque notably increases by more than 20% or 85N.m. Don't all e-bikes feature walk assist? 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. This adjustment has the biggest impact on the motors performance and your total range. Same with brose 2.1 & their motor failures. 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. Merida was the first to release a 2021 eBike running an EP8 and we've actually already ridden it in this video.For 2021, Merida has added the EP8 a larger 630Wh Shimano battery and improved the . By Ralf Hauser That rattle would drive me bonkers.

The cheapest Specialized Levo is the Expert model, which sells for just shy of $16K. If thats the case for you, start at Level 5 and work your way down a notch at a time. The lighter weight is a big plus as well. If youre sprinting at speed, the Levo feels sticky and lazy in comparison to the drag-free EP8 motor. As they say, power is nothing without control. Generally on bikes we spend so little time braking that regeneration would be a waste of effort. The belt-driven design is also a touch quieter when pedalling, and theres no clacking noise either. That said, wed prefer if there were more metrics displayed on the main screen to begin with, so you could ditch the GPS altogether. I have not heard of a recall, so I did some digging. Just remember to manually unpair your phone from the bike before you start riding again, as the motor wont engage while the system is paired to the app. The maximum rider support was raised to 400%, compared to the E8000's 300%.

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. 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. leftside; Nov 30, 2021; Replies 23 Views 4K . For a lighter pedal feel than the E8000, the one-way bearing has reduced its rotational resistance, creating a free play. The all-new Shimano EP8 engine takes a leap in performance, comfort and compactness. 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.

That's worse to, because 20kg dead weight doesn't contribute like 20kg of normal, muscle-laden body mass. Its also given us plenty of opportunity to identify all the little quirks, while getting a better impression of long-term durability and performance. The frame itself is unchanged, but an adjustment to the receiver hardware allows the bigger 630Wh battery to fit inside the same downtube cavity. The way the 2.2 motor smooths out un-smooth rider input is very impressive, giving it the most natural feel on the trail of any full-power motor weve tested. While the motor is both more sensitive and more powerful though, Shimano has done brilliantly to offer usable control of that power. A bike that weighs almost half as much as the rider. Theres still a whirring noise from the metallic gears inside, and the pitch increases slightly at higher cadences. . This simple concept improves the ride quality in all situations, eliminating the lurch forward and wasted energy as the bike accelerates while also continuing to provide additional assistance when the trail gets tougher and the rider works harder. 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. Filter. 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.

One of the more intriguing aspects of EP8 is the ability to fine-tune the motors performance via Shimanos E-Tube Project app. In the winter my range has decreased on the battery due to low temps, if I keep it in eco mode I get greater distance than boost and as I loose a bit of weight in can go further. Wowzers! The EP8 is also tuned to give more power in Trail mode without affecting range. It's really, really quite quiet. But even then it is still quieter than my saddle bag bouncing around. 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.

The biggest change has been with Trail mode, which now gives you access to the full 85Nm of torque if youre pedalling hard enough. 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. At 52+ lbs, you're going to be using that motor every pedal stroke. If you aren't climbing steeps and requiring the torque, you would get way longer distance. Our advice is not to rely on the range estimation in the first place. However, when coasting on rough terrain the unloaded system can exhibit a normal clicking sound that may be detectable to the rider. It's a powerful unit with a huge reach, but it has a little problem: it rattles when riding downhill or, simply put, there is no power on the pedals.

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. So many issues that can be simply solved by not having a motor. It's around 300g lighter than the old E8000 it replaces, as well as being much smaller in volume . 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.

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. 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. A bit like chain slap when you don't apply force on the pedals. By their own standards of non-assist components, this motor is not worthy of the shimano name. I have ridden ebikes great fun,addictive, you gain some things , but lose some things as well, like all bikes a compromise.

The SC-EM800 can also communicate with third party cycle computers through the ANT wireless protocol to display more detailed battery capacity and power output info in addition to ride mode, speed, gear position, range and odometer. Limiting the maximum torque is something youll notice more at low cadences in high-load applications rather than general trail riding. you should ride slow with a good cadence. Garmin shows 30% battery left, 900 meters elevation completed, 20km distance completed and the Garmin estimates I have 10km distance remaining (it actually estimates slightly higher as I have a bigger battery in the Meta, but these figures are close enough). Yeah you're right but I feel like the biggest factor is still rider weight. I rode an e bike and suffered a little bit yesterday.
