I can sense people's concern.. I've been taking things slow, respecting the bikes size and capability. I'm not a young guy (almost 37), so I've gone through my speed demon phase, and plan to simply enjoy working on these bikes and riding in the open air.
My gloves are not insulated, so I can really only be out for an hour or so, but managed to put on about 200 miles since Christmas (both bikes arrived in December).
