I use Bionx on my Mountain bike as a commuter. Yeah yeah.. I know... mountain bike. But part of my commute (midway) is a fun off-road segment that I go out of my way to do every time I get a chance.

I used to have a Strong eBike. That's an entire bike and it was just too damn heavy. too heavy to transport, too heavy to pedal, too heavy to be effective. Sure the motor was a 500W instead of the Bionx 350W I currently have, but it needed all that power just to get it moving. That thing was just not a good bike overall.

With the Strong you almost don't want to be pedaling because of the weight. With the Bionx, it's a joy to pedal.

Most of the time I pedal in assisstance mode 2 (75%). When I'm tired a bit I'll switch to mode 3 (150%). And if I have a hillclimb, even a light grade, I'll switch to mode 4 (300%) so I don't break a sweat.

I sometimes use the thumb throttle off a corner to avoid changing gears and just to get up to a speed where I can start pedaling on my own.

The regen is pretty cool as well. On one of my favorite trails there's a 500M long steep downhill segment. I put the Bionx into regen mode 3 and don't touch the brakes. Sure I don't go very fast, but I do make it to the bottom of the hill without having to use the mechanical brakes to control my speed. Just some taps on +A or -G to switch re-gen levels to control the downhill speed. It works!

While the Bionx is more expensive, it does give a lot back. No need for a cycle computer, it's all built-in. And the light weight truely is a strong selling point. Especially compared to the Strong GTS eBike.
