Lyft Inc is removing several thousand electric bikes from service in its bike-share program in New York, Washington and San Francisco because of a braking problem, the ride-hailing company said on Sunday.

"We recently received a small number of reports from riders who experienced stronger than expected braking force on the front wheel," the company said in a blog post emailed to customers on Sunday.
