Great bike for the money, only used it for short distances but happy so far.

My thoughts on my newly purchased Fiido M21.

This was not my first e-bike but was my first 'fat-bike' - and as an 'oldie' well into my 70's, it may have appeared something of an over-enthusiastic venture. It's turned out to be absolutely superb, the comfort, the 'sporting' response from the high-power motor, coupled with the smooth progression of power when starting to peddle, gives rise to confidence on the road. I'm now looking forward to a few years of 'fun-riding' - even if only to collect my prescription from the Doc's :).
