I have a long cable, good hard steel and coated, I use this in combination with a real nice U-lock. I will also be installing a hidden kill switch, one of the on or off switches.
im going to install my engine with quick-release bolts, and get a BIG FAT chain and paint it gold. Then when i go into a store i will just remove engine, attach to chain, put around neck and walk around like the junkyard dog.
