February 6, 20224 yr I’ve ordered the D21, can’t wait now to get the bike, thanks Cyclebuddy and Stormfeet
February 9, 20224 yr Hi! New to the forum. Has anyone got the new Fiido D21 folding electric bike? On paper it seems to be the Fiido D11 that's been out for a couple of years, but has an added torque sensor. Specifically I'd be interested if the speed limit (for assist) could be tweaked similar to the D11. It's not designed to be a fast bike, but a few more mph does help. Thanks in advance! Hi Stormfeet, When your D21 arrived did it have any weld issues. Mine arrived today with holes in the frame just to the left of the release catch for folding the bike. I’ve attached photos
February 9, 20224 yr That's neither right nor acceptable. Fiido's warranty policy is here. Email your photos and other details to them on the address given. It should be replaced.

I’ve phoned them today and emailed the photos. I’ve got to wait until tomorrow until they get a response from Fiido. I will be asking for a replacement. Thanks for the info
February 16, 20224 yr Author I've had a look at those photos, did not get the weld issue near the clamp. I do see a similar notch in the weld in photo 2 (seat tube meets top tube) but thought it was meant to be like that (for a cheap bike at least) Had had the D21 about 2 or 3 weeks now. It climbs small hills fine on assist level 3, even when pedalling in the highest gear. Downhill resistance of the Fiido is higher than normal-wheel-sized bikes, freewheeling is slow; I tend to get smoked downhill by the freewheeling normal pedal bikes. The Fiido climbs well enough to annoy them beforehand though! It's possible to be lazy and do the throttle-only gliding at 24km/h on flat ground, although that gets boring. The speed unlock trick (described above) definitely works, am getting a bit more than 15 mph on assist which is fine for commuting. Haven't managed to unlock the display (so my bike's display is still capped at 25 km/h), whenever I tried it reset the speed unlock so I had to do that again. It's no real bother, the bike will never touch 20 mph so no need to look at the display. Chain showed beginnings of rust, but a spray of ACF50 is an easy fix The D21 could benefit from folding into a more compact form, but other than that, I'm pretty happy with what it is and how it is.

Hi Stormfeet, I had a number of issues with the holes and chips in the paint. The shop refunded me £85 pound and they sent me an email to say that the holes are fine, no structure issues. I agree with what you have said above really good on hills but slow down hills. I use it everyday now and think it’s a great bike for the money and commuting on the train. Only had to charge the bike once in 7 days and the battery bar was still showing half. Only doing 9 miles day but with some good hills on the way.

February 24, 20224 yr Author Okay, first annoying bug found with the D21, specifically the spring located at the big hinge between the two halves of the bike, that which protects the internal cables from being pinched/damaged. Over a few weeks of use, my spring stretched and developed a wider circumference than it had originally. This led to the spring being unable to retract fully into the frame when the bike unfolds, and wedges itself preventing the 2 halves from clamping tightly shut. Pretty annoying. Called the dealer and was advised that this is rare but not unknown, the solution being "turning the spring counterclockwise while pushing it back into the frame." Alternatively, to cut the spring and replace it with a plastic cable-holder off amazon. Was assured this doesn't void the warranty. My spring is too wide now for the first option, so shall report back when the new cable holder arrives.
February 25, 20224 yr ...my spring stretched and developed a wider circumference than it had originally. If you look at the spring, the ends have bigger windings. It can have a tendancy to "screw" or pull it's way through the frame holes. In the extreme, it can get trapped and distort to the point you can't fold/lock the frame back together (or so I've read). You can buy new ones for £6 from Fiido, but the issue is feeding the cables through the spring. Knowng this can happen, I check mine and wiggle it back every now and then. Like wheel spoke tension, you just need to keep an eye on it.
July 20, 20223 yr Looking at buying a folding ebike (research phase). I was looking at a fiido d11 and d21 but then I read all the legal stuff. If I’m reading it right to be classed as an epac in the uk the bike should have a ce sticker so it complies with the EU rules which include max motor 250 and no throttle pedal assist only. So I figured fiido isn’t compliant and so you might end up in trouble if stopped by the rozzers. I found the himo z20 max which does include a ce sticker and has had the throttle removed to comply with the rules. Does the fiido have a ce sticker? No Throttle? If it did it would be my top pick due to its weight otherwise it’s the himo z20 max for me I think

If it did it would be my top pick due to its weight otherwise it’s the himo z20 max for me I think I believe it's a twist throttle (with sustained power) that's not allowed. The D21 has a thumb throttle. There's printed text on the motor itself stating 250w. They sell such stickers on Ebay though. But with the tiny motor size it's pretty clear it won't be a bike physically capable of naughty speeds (unlike a 750 watt motor which is much larger). I've ridden past countless police in London who don't bat an eyelid. The D21 is available via the Cycle-to-Work scheme which means it's vetted for legality
July 20, 20223 yr Does the fiido have a ce sticker? No Throttle? Do you mean an EN compliance sticker? My D11 does have a CE sticker. As SF says, 36v 250w to show legal compliance is clearly printed directly on the motor (not a label). The thumb throttle is easily/simply unplugged if it worries you.
August 10, 20223 yr The D21 is available via the Cycle-to-Work scheme which means it's vetted for legality Any chance you know which one? None of the dozen or so sights I've found fiido or himo on have offered the scheme Many thanks

August 10, 20223 yr Vive Scooters was the shop i got mine delivered from Thanks! Was actually one of the sites I looked on but dismissed because didn't see any mention of the scheme. Have contacted them directly to confirm but assuming for now they no longer offer it :-(

Have contacted them directly to confirm but assuming for now they no longer offer it :-( I'm told that Green Commute Initiative is a decent alternative to the cycle-to-work scheme, and that it's quick and easy for shops and customers to register with.

August 10, 20223 yr I'm told that Green Commute Initiative is a decent alternative to the cycle-to-work scheme, and that it's quick and easy for shops and customers to register with. I'll check it out because there is a chance my work won't introduce the cycle scheme. Hopefully then this GCI is an alternative. The company got back and confirmed that they sell the bikes on the scheme! So now down to waiting and hoping company introduces this.

I had a brief look at it, and I'm no expert at all about all of this, but why would an employer potentially reject having a cycle 2 work scheme but accept green initiative one?
