Frame size
By most bike sizing standards a UC Pro medium frame is really a large frame. I've compared the dimensions of my medium UC Pro with other medium commuter ebikes and my UC Pro's frame is considerably larger.
I also took the bike into my favorite local bike shop and they also said, after taking measurements, a large frame.
Over 3 or 4 months Pushkar and I had come to an agreement that I would send back my medium UC Pro and he would build me a small sized UC Pro. Note that the main reason the bike is going back is the shifting problem-the frame size is secondary. When the small sized titanium frames arrive he said the small sized frames were almost the same size as the mediums. He said it looked like they were built incorrectly and that the changes would be made for the next titanium frame shipment.
God only knows when the next batch of frames will make it to Boston.
Shifting
I've come to the conclusion that my bike will never shift properly in all of its gears. Never.
The frame's super-wide rear hub spacing makes it impossible to install a regular derailleur and have it shift properly. My bike's frame originally had a 3 speed hub, which, I suspect, worked well. I don't think the bike was ever designed to work with a regular derailleur.
The mechanic at the bike shop I frequent, who has 18 years experience working bikes, said he had never seen a bike with such a large cross-chaining.
FnF, I'm wondering if my old-framed UC Pro was actually a CT? Is there more of a difference besides the super wide rear hub between the two models?
Final note
I took my UC Pro for a 55km ride today (the rain stopped!) and I have to say this bike is a joy to ride. It's
very comfortable and the power is addictive.
I rode up a REALLY steep hill during my ride. I don't know what degree of steepness this 1 km hill is, but only a handful of riders on regular bikes have made it all the way to the top without getting off and walking.
I rode up in level 3 (I have mine set to 5 levels) and the bike flew up the hill. With some of the steeper parts I hit 1300 W.
This like is turning out to be my favorite bike. If I could use all of the gears and the bike was a bit smaller it would be almost perfect. I say 'almost' because I'm still think it looks a bit DYI, but that becomes irrelevant when I ride it.
FnF, you're going to love this bike when you get it.
