### ⭐⭐⭐⭐⭐ Nice forck for my fat e-bike
*by V***D on 12 September 2022*

Noting to add ,just perfect match.

### ⭐⭐⭐ Budget friendly
*by S***S on 28 January 2025*

Not the best, but they do work, good enough for leisure rides but wouldn’t recommend for anyone wanting to get serious off road. They do look good though.

### ⭐⭐⭐⭐ Air shocks
*by C***Z on 23 June 2023*

Nice pair of air adjustable shocks ( not the fake type that some sellers offering) Have to thank another Amazon buyer for the video showing indeed they are adjustable . Bought as soon as I saw video . Just had to cut down the centre tube as way to long . Comes with star nut. Unfortunately I gave it 4 stars as no manual supplied so having to rely on internet searches as to min and max psi for riders . I did ask seller for info , but as yet no answer . Such a shame otherwise it would be 5 stars . At least no waiting weeks for items to be shipped from other sites .
