With my R - 20 I carry a very secure looking Kryptonite U-lock Evolution Vds AND a small vinyl covered wire cable lock ( cheapo) for the wheel-to-frame. Its the only bike I ride which requires TWO locks. The frame Q/r has been replaced by a Bolt. I see a lot of people fold their bikes and THEN lock them up making a tighter package & for the lock to cover more ground.

Might buy a Swift soon which I will probably lock-up the same way.
