iSinwheel U4 Foldable Step-thru Electric Bike

I purchased this bike as a mode of transport for work . It would normally take me around 40 minutes to walk and 20-30 minutes on public transport . With this bike it takes me 10-15 minutes.
It’s amazing !!! I absolutely love it !! At 53 I’ve experienced some health issues and was struggling to recognise who I was becoming . This bike has given me a new lease of life. I feel like a teenager again ! It’s fun very quick (using this throttle) and the assisted pedal is a great asset. I used to thoroughly enjoy years ago and this wonderful bike has given that thrill and enjoyment back to me .. highly recommend great little town bike easy to ride and navigate and handle .
