I am getting old and a little unstable - balance is kind of wonky due to brain trauma. I keep on crashing my ebike. I've had a few nasty events and I think it is time for a trike. I am on Social Security but I have saved enough to purchase a tricycle. I do need some guidance on a model that uses a 700C front wheel/tire that I can re-use from my ebike. I stay on pavement (except when I don't ;-) ) Any recommendations on a sturdy trike that I can Bafangify? By the way, I am a big guy - 6'2" and 270 lbs.
