Fun, photographs, facts and figures - 2WD

[ChinaPhil]

Like many on this forum I enjoy the process of researching then building e-bikes but ultimately my goal is to ride to locations where I can indulge in other hobbies such as sightseeing, photography and video. These journeys normally involve hill / mountain climbing and my bikes have to have visual and audible stealth; I always ride with behavioral stealth.

Yesterday I rode here:

Bout 21mph.. that's pretty good for those little geared motors. I bet you could go faster pedaling if you changed to a lower rear tooth or bigger front chainring.

I bet that thing climbs like a monster, am i right?

Sounds like some cool rides man.. you need a vid cam to show it off. Always in envy of the big mountain bike setups.
