I love the GrooveFather! Been checking him out a lot over the past year.   

This guy is insane  

Weight of an e-bike is somewhat of a moot point aside from lifting it onto a rack or bike stand. Another thing many people don't realize is that an e-bike doesn't mean less work when pedaling aside from climbing which is where you want the assist but on flat trails you need to keep pedaling or the bike becomes an anchor. You can actually feel it slowing down when you stop pedaling so you always need to keep pressure on the pedals for the assist to work which actually is more of a workout than you would think because you can't really coast like on a regular bike.

Sounds so damn close to the original- wow!
