These are a huge upgrade from mechanical wire brakes. It is a quality set of components. The only issue I had was the front cable length wasn’t long enough. My e-bike folds and there wasn’t enough length to allow folding the handlebars. I bought another cable and not it is perfect. Just be sure to double check the cable lengths before your purchase. I didn’t do that. Nothing wrong with this brake kit. It has been great.

Excellent, quality, performant brakes.I would not recommend changing the cable length yourself unless you know what you’re doing and have a dedicated hose cutting tool, but that’s more about my own hubris than the product.I’m not sure if the pads are proprietary, so that’s a slight con, but they work well and are relatively cheap.The one real annoyance with these is when it comes time to bleed them, things will get a little messy.For the price, you really can’t go wrong.

The brake kit is well-made with high quality materials. Comes with everything you need to install the kit, plus some extra screws.The braking feels fantastic, it responds to my inputs quickly and effortlessly. I feel much more confident riding my e-bike in the hilly area.Pro:- The kit is pre-filled with mineral oil, no need to buy them separately.- The only 2-piston option at this price point.- Motor cut-off switch for e-bikes.- great rear cable length for folding e-bikes.Con:- The front brake line is a bit too short. While perfectly usable, if you have an adjustable handle bar, you can’t bring it as high as you used to.- You have to manually connect the brake line with the handle bar on the rear brake, which can be tricky.Overall, I recommend this product to someone who owns an e-bike and would like to invest in their riding safety and the bike’s performance.

Replaced my wife's cable brakes on her Lectric XP lite with these. Install was super simple and the front brake line was long enough for the extended height of the front handlebars if you use the stock giraffe neck. I had replaced her neck with the turtle neck shorty and a set of Fenix BMX bars, so the line was just a bit long and I had to cut it down. Rear line was A ok. Be sure to seat your pads correctly right after installation. I have not had any issues with brake squeal after completing a proper pad bedding.

The only thing I didn't like was the fact that the back brake line is a little on the long side for a 2019 Rad Rover E-bike. If they had included another "barb", I could have clipped the excess and I'd be COMLETELY satisfied.That said, these are the best brakes I've EVER HAD on a bike. I can skid the back wheel (which would never happen with the cable brakes), or even do "stoppies", with the front. You won't regret the performance of this brake set.
