ZTZ 20/26 inch 4.0 Fat Tire Bike Air Suspension Fork - 180mm Travel, 135mm Hub Spacing, QR 9mm, Double Crown Shock Absorber Fork for MTB Fat Snow Beach E-Bike

I was scared to buy and it wouldn't fit my son's ridstar q20. But IT DID! perfectly! Easy to install also!

Great for the price!, only thing is the stem is to short. I would recommend doing your research before buying for a larger bike or ebike

These shocks are amazing! Although there are some things that are minor that could be improved upon. The first problem is there was nowhere to mount the headlight to as the fork came with what looked like. Should be an installation hole or mount for the nut or screw for the headlight, but it was just solid metal I had to drill through it in order to mount the headlight. They did not include hardware as in screws for the fork to mount the fork to either.

Over 1000 miles in these forks I run 20 x 4.25 tires with these forks I don’t jump ramps or any hardcore stuff but I do ride hard daily and by hard riding I mean hitting the brakes and going 50mph these forks can handle it almost 8 months with them and not a single problem

The media could not be loaded. fits nice on my bike, really soft, and looks badassAN UPDATE, JUNE 24, 2025Months later, ive been abusing these forks for so long. Other reviews say that theirs broke under low speed, though for me, ive been taking them to jumps, trails, wheelies, pump tracks, everything. Not once have these forks failed on me. I usually drive around 33 mph, occasionally popping wheelies and jumping off hills. Around every month or two, you want to make sure you refill the forks as usage can sort of decrease its air content, so beware of that before you bottom out. The best setting i reccomend is 5 clicks, as it is not too soft but also not too hard. These forks are a go to, though know your limits

Don’t buy. I tried to give it the benefit of the doubt even after seeing bad reviews. I bought the fork and had it installed by a professional. My main concerns were the dropouts where the axle meets the fork. That wasn’t the issue at all. When testing, I was super gentle and it was riding really smooth and way better than oem like I was on a cloud.I have a 70lb ebike - plus 150lb rider. I was going 21mph, flat and smooth road. I felt something in the handlebars and next thing you know I was under a car with blood dripping off my face and arms. I never took this thing off road or on any jumps or bumps or anything. I’m okay but it could have been way worse if I wasn’t wearing a helmet.Funny because my tire stayed in place, seated on the fork real tight, but the handlebar cast broke going 21mph. I learned my lesson. You get what you pay for. If you are getting a 20-40lb bike and you go under 15mph , maybe this is for you if you’re careful and not riding offroad. But for Ebikers and MTB/BMX out there, do not buy!!

Good quality for fat tire e bikes

Easy to install
