I have a pair of recumbents and I have difficulties locking them safely when I have to park them in the street for long period of time. The conventional wisdom is to use a U-lock to attach the frame to a strong fixed point. With a recumbent this is very difficult because:
- the width of the seat will move the frame away from fixed points,
- the frame itself sometimes has no closed loop like the diamond frame of upright bicycles.
On my Nazca Pionneer there is a small closed loop on the rear stays so I manage to secure it with a foldable lock. This is weaker than a U-lock but it is the best I came up with. But on my Challenge Seiran SL, which has no secure point, I am still looking for a safe way to lock it.
How do you manage this?
