Between the driveshaft and front motor hub, probably a long way from being a normal bike.
The drive shaft is low maintenance but heavier and less efficient than chain drive systems.
There are conflicting opinions on reliability relative to chain, but I'm inclined to view it as the more reliable approach. The electric hub combined with driveshaft system might make this a fine commuter.

Or a good techno-geek toy.


Any idea whose front hub system this bike has?
Also, how expensive is this?
Which Nexus hub 3/4/7or 8 speed?
