When y'all stop to eat, take pictures, shop or just walk around to sight-see and smell the roses, do you lock your trikes? If so, what do you use and how do you prefer to secure it? I was looking at a thread started by Idaho about his cargo rack, and YamiYuki showed a picture of their rack that looked like a U-Bolt lock hanging down from the framework behind the seat.
As to the type of lock, an old-time bicycle repair guy once told me that all bikes weigh about the same, because a 49# bike only needs a 1# lock, while a 5# bike needs a 45# lock. That, plus he also said any standard locking system is only there to "keep an honest man honest". On my DF bikes, I always used a cable with a combination lock, and while the U-bolt probably gives more security, it is much more heavy, so there's that trade-off.
Anyway, I often see people in videos getting off their bikes and trikes while out on their rides, and wondered if they secure them or not. One friend that rides with her 2-wheel roadie friends, told us that when they are planning a ride with meal, shopping and sight-seeing stops, they ride their older, spare bikes, lol. Since I'm an old married guy hoping to retire next summer, I haven't been able to afford a first, primary trike yet, let alone a spare trike, so there goes that idea, lol.
