The trike I'm considering has a straight frame/boom. No rear triangle. No loops or areas to pass a u lock thru. I could put a u lock around the boom in front of the steering, and it wouldn't lift over the front der. post/cranks, but any u lock there is going to be coming out vertically and I can't figure out how it would attach to a vertical pole/bike rack. Since I will be locking up at shops for 30-60 minutes at a time, how in the world do I secure the frame to a rack? I can secure the QR rear wheel easy enough, but the frame has to be secured somehow. The black seat adjuster bar is the only open loop and it comes off easily on each side br removing the bolts. Hellp!
