The Fiido D11 foldable electric bike – CleanTechnica Review


The Fiido D11 is a hot little foldable electric bike that brings together a unique seat post battery with an innovative modern frame design into a nice compact package. It looks and rides a bit like a Brompton folding bike, but with a nice pinch of technology that sets it apart.

The D11 caught our eye because of its appearance and its technical data is also solid. It has a 250 watt motor, which is often used on compact bikes like this one, mated with an oversized 11.6 Ah battery. That might not sound impressive compared to the batteries common in large electric bikes, but for a small 39-pound folding bike with a 250-watt Xiongda rear hub motor, Fiido estimates the battery takes a rider about 50 to 62 miles without power is stepping. They call it moped mode, and after riding the D11 around town, I’m officially a fan.

I usually prefer to pedal, and the D11’s 7 mechanical gears offer at least a bit of flexibility in this area. The rear cassette has a 14-28 tooth range and offers a decent range of gears for everyday driving, but they won’t help you conquer steep hills without sweating a bit in the business.

The extended seat post offers generous height adjustment to make it easier for riders of all sizes to get on. It would be nice to have a height-adjustable handlebar with it, but its fixed height is usable. My older son (4’8 “) can ride the bike with the seat fully down, and at 6’2” I’m at the high end of the bike height range. That’s an enormous range for a single bike and definitely one of the D11’s strengths.

As a compact folding e-bike, the D11 was mostly assembled. We just unfolded the bike, attached the fenders and after a few quick adjustments we had it on the charger to get it ready for the first ride. The ability to fold up without disassembly is certainly an advantage for anyone looking for a bike of the right size for homes, city life, motorhomes and boats, to name a few use cases.

Riding the D11 begins with the seat post battery plugged in. A coiled cable leads to the top of the seat post and allows the saddle to be adjusted widely. After plugging in, briefly tapping the power button switches on the battery and the integrated rear light. Finally, press and hold the power button on the handlebar-mounted display to turn the bike on. It’s easier than it sounds and before you know it you’re in the races.

The handlebar-mounted display shows the current speed, the pedal assistance from one to three and the charge level of the battery. It’s nothing special, but it does the job.

The D11 is light-footed on the open road. The narrow 20 ″ x 1.75 ″ tires make it agile and lively on the bike path, no matter how much pedal assistance is provided. With the throttle grip, the 250 watt motor provides an impressive power boost on flat terrain and provides support uphill with a slight tailwind. It’s great fun to drive and on our test track it did the stated range even though we pedaled rather than using moped mode most of the time.

The built-in lights and mudguards add nice functionality beyond what many e-bikes offer. I think it’s particularly great that the rear light is embedded in the battery of the seat post.

Speaking of the battery, it’s a brilliant solution to a few different problems. First of all, it’s easy to remove the battery to take to work, home or apartment to charge the bike. The seat post has a convenient form factor that can be easily pulled out without pulling out a key or the like. Second, inserting the battery into the seat post encourages owners to take their seat with them, which urban cyclists often do to prevent theft, killing two birds with one stone.

Overall, the Fiido D11 is a nice entry into the compact folding e-bike category. It’s beautifully designed and has some thoughtful features like the battery in the seat post and the nice, functional folding frame design that really make it stand out from the rest. It offers an impressive range per charge compared to any single competitor in its class we’ve seen, and offers more range in moped mode than most full-pedaling e-bikes.

With the current retail price of 999 US dollars (normally 1,299 US dollars), it is in the middle of the compact folding e-bike segment. The price is a premium compared to other bikes of similar quality, although the larger battery, range, detachable seat post battery, and beautiful design add to the value of the D11.
