I would say that for many roadies, the only way they'd get an electric assist bike is if it topped at 45 kph or 28 mph. This would classify it as a Class 3 - which would make it a moped or scooter for registration purposes. I'd bother to get the license if I wanted the ebike, but the speed...

I ride a variety of terrain with varied wind speeds. I'm about 200 pounds. Decidedly average fitness. Use Giant's Syncdrive which is a PW, and Syncdrive Pro which is a PW-X. On flat terrain with stop-go traffic on Eco and some cargo, I'd say about 100 km with about 30% left in the tank from...

They're probably holding back a bit in order to please their company clients. This way, they can sell their own bike line, but also say that they're not using absolutely cutting-edge tech, so they're just picking up the back line. Their company clients are free to exploit the higher end of the...

Yamaha's 1993 introduction into the ebike scene was significant because as far as I can tell, that was the first instance of what we would call a modern PAS. Older models from Panasonic and Sanyo used a concept more similar to an electric moped.

For cadences, I'd say the science is right on the money. For most amateurs, higher cadences probably are counter-productive, especially when you have electric assist. When riders say higher cadences "save their legs," it's usually in terms of damage and fatigue, which compounds higher when you...

It's actually quite good for commuting because the motor delivers very good torque all the way down to 60 rpm so if you're just slammed at the end of the day, you could just put it into Sport and just lazily spin the pedals around while you cruise home. I've done that once or twice and it works...

It's the Giant Syncdrive Sport. I usually do between 80 and 90 RPM and I don't note a dramatic power drop-off within that range, even on the highest setting and on a tough incline. It might be specific to Giant's implementation of the motor. I can't say anything about any other implementation.

I'm only reporting how my bike performs based on how I'm riding. It says there that there's a sharp drop-off between 80 and 90 rpm, and neither my experience nor the power meter on my bike is consistent with that chart.

I'd broadly agree with JayVee. I am a roadie by preference and I only recently sold off my road bikes after 2 years of not using them much after I got my ebikes. I prefer cycling at 80-90 rpm and the Syncdrive Sport (PW Yamaha motor) on my Giant performed well under those conditions. It does...

It's a little meta, but I think Court is doing a pretty good job of staying as neutral as he can, knowing as we do about his personal preferences. A lot of people wouldn't be as charitable in the same position. He does represent a segment of the market (people with knee issues) for whom electric...

I come from a roadie background, and regardless of efficiency, I prefer to pedal at a higher cadence - about 80 to 90. Sometimes I try to accelerate by pedaling faster, but that's unusual. I have both the Syncdrive Giant motor by Yamaha and the Syncdrive Pro. The PW based motor does offer full...

I just got one of these babies to serve as my daily driver while the Dirt E2 is in the shop for servicing. Nothing too much wrong - after 12k km, I wanted the bike serviced to possibly replace a BB bearing, get the display checked for fogging in the rain. The Trance E+1 Pro of course, is built...

Going on two and a half years of commuting on the ebike. Over 12000 km on the odo now. I'm not sure exactly what because the odometer stopped at 9999 km and I don't know how many km I logged before I noticed. The news on the bike is that there is no news. I brought it into the shop for servicing...

I bought a Dirt-E2, one of the lower specc'd bikes in the Giant line, for about $2000+. I cannot stress enough how important it has been for me to have a reliable bike and a reliable LBS to service and maintain it. Giant and Yamaha parts have been phenomenally reliable, and the LBS comes...

Amiti E is a mid drive using the Yamaha PX motor tuned by Giant. It's similar to the one I use on the Dirt E. There is a slight resistance when the motor is off. It doesn't feel completely smooth. Having said that, I have ridden the bike without any assistance and it is perfectly rideable if...

https://www.giant-bicycles.com/int/quick-eplus-fs-45-2018 Could just get the one with front suspension.

I own and use the Dirt E+2 and I've used it over 2 years. Trust me, you're not losing anything without the display. At worst, you'd need a separate speedometer. Probably get that. It'll be removable and easier to replace than Giant's proprietary display. But the thing about it is that it sticks...

Range depends on how hard you pedal. Obviously, if you pedal on your own, the range is functionally infinite. Giant's implementation of the PW motor system is fairly good. I have a 400 Wh and a 500 Wh battery. I bought the 500 Wh one for $500. As far as I can tell, the depletion on their...

For a specific test parameter, ebikes do save you from sweating, so you get less exercise. This is absolutely true. This is relevant to training and commuting because there are times you want to be able to cover distances with less effort or with modulated effort. Analogously, lifting a 50...

Mostly Eco. I use Power on the Yamaha PW motor when I'm climbing something steep and I don't feel like pushing. Also when going to work. Whenever I have the time and I feel like pushing, I switch to Eco. Sometimes, I turn off the motor. Depends on how much time I've got.
