I have a felt 29er with the bosh bb based system.
I have been using it for over a year and it is really fun
Cannondale has licensed this system too.
Charge time is reasonably quick and ride distance seems to be about 35 miles on a single charge.
I am typically pulling one of the 2 trailers shown. It really has some pulling power and it can easily move my 200 lbs and either of the trailers. The tool version is well over 120lbs loaded.
This thing is a lifesaver after digging for 3 hours.
They don't have enough torque to wheelspin on the dirt. I am sure this is by design.
More e bikes were sold in Germany than pedal bikes in 2014.
Felt also makes a fat bike version
People love to hate these things, but I think they are harmless and fun. As someone who rides Moto, this is no motorcycle. It tops out at 19.9mph and it weighs a million lbs.
We sell the commuter versions too.
They are coming in a big way and the bike industry as a whole had already embraced them.
I can absolutely crush traffic and average 20+ mph and barely break a sweat. I can also regulate the power output and get sweaty if I like.
Let the flaming begin.
This is the felt cargo bike which may be right up your alley.
