on my Ridstar Q20, and it made a huge difference in ride quality. The stock fork on the Q20 is decent, but this upgrade noticeably improves shock absorption on rough terrain. The 180mm travel handles bumps, curbs, and off-road trails much more smoothly. Installation was pretty straightforward as long as you match the 9mm QR and 135mm spacing correctly. The air suspension is adjustable, which makes it easy to dial in for your weight and riding style. I really like the manual lockout feature for switching between street riding and off-road use. It feels sturdy and well-built, especially for the price point. On longer rides, it reduces hand and arm fatigue compared to the stock fork. It also gives the Ridstar Q20 a more aggressive and premium look. Overall, this is a worthwhile upgrade if you want better comfort, control, and performance from your Q20.

They work good but a little weird

These were great! The fit and 6-9” stroke sold me- flashy gold forks helped sway me too! But just 5 months later while riding fast 34 mph; I stopped at light, then at green accelerated; the frinkin’ bike frame disappeared out from under me! All had was handle bars for a few steps then the wires ran out and face plant! It sheared off at the top crown! See photos. I jury rigged it to get home see photo with bars re-mounted temporarily.

I put them on my ridstar q20 and they are amazing. If there is a local Pedago ebike shop near you, takei t there I had him put mine in for $50 and he did an amazing job. They arent fit exactly for ridstar, over time it will adjust to fit you just need to keep tightening it when the star nut becomes loose but the guy at pedago told me to keep coming in and he will keep tightening it. So recommend pedago and these forks they are also very light, which mean great for wheeling.

Got for my grandson and he loves this. He said his bike is older so might have to cut down size but no problem.

Our son got an e-bike a few months ago, and unfortunately, he was hit while riding (thankfully, he wasn’t injured), which bent the original suspension. After some research, my husband found these suspension replacements—they fit perfectly and had excellent reviews. Installation was easy, and my son says they feel even better than the original suspension on the bike. Overall, a great upgrade and highly recommended for anyone needing replacement or improved suspension for their e-bike. The comfort is amazing and the looks are even better. We feel the value of these is definitely worth the price.

Nice fork. Unfortunately the gold version has wider axle shoulders than the black (visible in stock images) and the stock 9x135 skewer does not work. Emailed bucklos for advice. I’m not having any luck sourcing a 9x145-150mm nonQR skewer.

If you are looking to upgrade your folding ebike shocks and handlebars/neck! These are worth looking into! Caution for Engwe EP-2 PRO users... This is not a threaded design and therefore you must swap out your race and neck setup to accept the better design, and this fork is a post fork for calipers not the IS standard that came with your bike so you must buy the post mount caliper bracket for 160mm rotor in front.
