Besides the factor is, the Shimano EP8 additionally extra highly effective than the E8000. Shimano claims it could actually provide as much as 21 % extra torque, maxing out at 85nm as a substitute of 70. And there’s better heat-sync floor space and extra refined heat-management software program, so the motor is healthier in a position to deal with the warmth buildup of that additional torque. On prime of that, Shimano claims 36 % much less drag within the motor, so it’s extra environment friendly, transitions smoother when help stops, and pedals extra naturally when help is off.
The software program controlling the help itself has been refined too, now beneath the perplexing identify of “E-Tube.” The E-Tube Undertaking smartphone app permits riders to regulate energy curves in every setting, restrict torque and alter the way it begins off. It permits riders to have that half-an-e-bike expertise provided by the Levo SL that places effectivity over energy. Or, after all, they’ll go for a extra conventional full help. All through all of it, Shimano has refined the algorithms that translate enter to output. The connection between your torque and the motor’s torque is claimed to really feel extra pure now.
However right here’s the unhealthy information, and it’s in all probability worse than you assume. The Shimano EP8 system isn’t the sort of factor you’ll be able to improve to on an current bike. The body needs to be made for it. Take into consideration the ramifications of that for a minute. It’s as if when SRAM Eagle got here out, everybody who wished it wanted to purchase a brand new bike. As a lot as we complain about new requirements, this doesn’t occur in our business that usually. Certain, there’ve been refined issues like enhance spacing or tapered headsets that body producers had no selection however to undertake. However not since disc brakes has a part doomed each bike that got here earlier than it to ceaselessly being second-rate. And this may seemingly be the truth of e-bike evolution. As a result of the scale of the motor and battery is such a battleground in e-bike improvement, it’s potential that, at the least for the subsequent few generations, each important motor improve is not going to be backward-compatible with present bikes. How would you’re feeling when you simply spent over $8,000 a Santa Cruz Heckler? It wouldn’t be Santa Cruz’s fault. And even Shimano’s. It simply could also be a danger that e-bike clients must get used to.
