Bike for Smart Trainer?
I'm thinking about getting a Smart Trainer (thinking direct drive) to keep me active during the winter. Generally, I abhor indoor training. When I used to (be able to) run, I called that dang thing I was forced to run on in bad weather a "dreadmill." Since the old age injury (don't ask) and cessation of running (used to run 20-25 miles/week purely for exercise), I've picked up an eBike and I LOVE riding it. But winter approaches (it's here) and Zwift looks like an amusing option to keep me more entertained during indoor workouts. So I'm looking at a direct drive trainer. But alas, I have no bike for it (the eBike is way too heavy and not worth removing the rear wheel since I might use it on warm winter days). Any suggestions for a cheap bike to drop on the trainer? Get the cheapest 22 speed from Bikes Direct and toss the rear wheel? Get a cheap frame and build up the parts needed for the trainer (cheap front wheel, drive system, bars, seat)...I've never done this, but I am mechanically inclined? I don't actually intend on riding this bike outdoors. The Kickr Bike looked pretty K-Rad but dang pricey. Thoughts? Ideas?
