@Jarrett how do they work? Is it a throttle like a m/c or just the bike sense you need help and assist?
They have all flavors. The ones we have are pedal-assist with levels.
Off is no assist
Level 1 is 33% assist
Level 2 is 50% assist
Level 3 is 100% assist
So you can tailor your ride a bit. If you want a workout, leave the motor off. Or put it on Level 1 only. If you just want to easy cruise around, leave it on Level 3.
When I ride I do all the above. I don't shift gears as much as I did on a non-powered bike, but I do constantly adjust the power level setting to get the ride I want. When I'm going up the 15%+ grade hills of NB, I definitely have it on Level 3. The same hills the bikes will coast down at 40 mph. They have good brakes on them as well.
I rode another brand the other day that had 5 levels of assist and the 6th level is full throttle control just like an electric motorcycle.
If I remember correctly, these are the legal standards for the bikes in the US. Think its:
Class 1 pedal assist to 20 mph
Class 2 throttle up to 20 mph
Class 3 pedal assist to 28 mph
The bikes we have are pedal assist to 28 mph, meaning when the onboard speedo hits 28mph, the motor cuts and you are on your own if you want to pedal the bike faster than that.
But of course, you can mod them to do more than that. There is one out there called the Ariel X-Rider or something like that, which has full throttle up to 36 mph or so. Saw a couple ripping through the streets of NB on them the other day. They kind of make an e-bike for everyone and every purpose at this point. The line is getting very blurry between e-bike and electric motorcycle at this point.
