Having recently used a Lime bike for the first time, I think I can understand why there are certain hotpots for bikes being dumped in large numbers.
The app controls the amount of assist the bikes give riders along their ride reducing this and the max speed in certain higher risk areas.
Unfortunately this seems very badly thought out, and the bikes cease to function at all in certain areas, and give dangerously and frustratingly low amounts of assist in others. The South Circ for example is limited to 8mph. I'm sure this is what causes some riders to reach a certain point and just stop. At 21p per min, you don't want to pay that to push a tank up the road.

They have their use, but certainly need more managing of where they can be left without penalty.

Definitely a LOT more appearing now though. Maybe the station would be a good hub, or the old bus stands on Westbourne.
