So I finally got to ride one and wow they can really go. My favourite feature is probably the worst feature and that's that you can leave them anywhere. However what I didn't realise until actually riding one, is that the app asks you to take a picture of where and how you parked the bike when you're finished and then potentially punishes people who don't park the bikes properly. They can clearly enforce that more. But now I'm of the opinion that the local councils need to provide more bike parking. One or two parking spots at the end of every road would be enough. Being someone that lives in a hilly area, I don't really bother with bikes, but with the electric motors on the Lime bikes, I would ride everywhere and happily switch from Ubers if they were officially operating in my borough. Anyway, they're really really fun and I'm really looking forward to them redressing the balance of cars in London. For short journeys, they're perfect and the more people that access them, the fitter the city will be.
Apparently it's not difficult to overcome the lock when you're stationary. And once you're moving, it doesn't re-engage.
