This would be a world beater IF the wheels were better quality. The spokes are too thin and weak and the drive side rear spokes break constantly under pressure. This is a real pity because, other than that, the bike is superb. It's comfortable and nippy and very enjoyable to ride, pedal assist and full electric modes are really good and battery life and range are excellent. But. I've spent far too much money (approaching what I paid for the bike in the first place) on repair work over the last year and I'm having to have a custom rear wheel made to see if this will fix the problem. If not I'll have to look elsewhere for another bike. Surely mag wheels would be a more sensible option - the smaller bikes have these and I haven't heard any complaints about them. If I'd known then what I know now I'd have bought the L3 - and I've already spent much more than the cost of one on this bike.
Having said that, I would buy Fiido again (so much of the design is spot on), but only a model with mag wheels.

Can't believe how good this thing is. Highly recommended
I bought the fiido d4s around 1 year ago. I've currently done 500km with no problems.
The only slight negatives are the brakes are not good, and the charging port has come loose
Other than that, it's a great bike and I would order another one without hesitation.
