Hi David
I've owned a Momentum Electric Upstart for 2 years I think. I bought it second hand, and it had been modifyied. The torque sensor was ditched as the seller said it wasn't responsive enough. He fitted a throttle controller in its place. I enjoy riding it & put about 500 miles into it over 1 year. The battery would get me a good 20-30 miles too. I recently upgraded the hub gear to a Shimano Nexus 7 as I still like to ride unassisted quite a bit, and the Automatix hub was a little limiting up hills. I wish i could have tried the torque sensing sytem as I've heard its great but a throttle suits me fine. I found the whole bike really study but quite a hard ride on rough roads, due to its weight.
