Lime has withdrawn its e-bike operations from Bromley. The company changed its app last week to prevent hiring in the borough after Bromley Council told it to stop. This decision followed an incident where a blind man, Jason Beal, 53, was forced into busy roads to navigate around e-bikes left on pavements in Penge. Mr Beal described the experience as "very frightening". Lime had been operating in Bromley without a contract with the council.

The situation raised concerns about pedestrian safety, particularly for disabled residents, due to improperly parked e-bikes. Bromley Council had previously raised concerns about Lime operating without consent and stated it would remove bikes and charge the company for costs if operations did not permanently cease

However, the picture for accidents has moved in the opposite direction. 1196 cyclists were seriously injured last year, an increase of 21% in just one year.

Editor’s note

AI hype is still running faster than some of the real world benefits but there is certainly signs everywhere of how it’s changing the business landscape.

Not just where money is being invested but also the mechanics of how companies are being formed.

The beauty of the SaaS financial model is up front cost but those costs do not grow in line with user base. With AI as users grow so do your costs. Perhaps a fundamental that may have been missed my many investors?

I’m still struggling to see how investors will see a return. Shhhhhhh don’t tell the markets.
