My kit was a birthday gift after the one my husband selected worked so well for him. We appreciate that we can pedal when we want and get assistance when needed. We chose to have a professional do the installation. While our model is not the fanciest it is easy to use, recharges quickly and meets our needs perfectly.

I highly recommend this system to anyone who will listen and have two co-workers with similar set-ups now. We all seem happy with the products but I can't really speak for them. I am thrilled with mine and enjoy heading straight up the two hills in my evening commute. Impossible to beat this system at this price!!

Finding a solution for biking can be hard after major health issues. But I really wanted to get going again but had less energy and confidence. They helped out and found a solution to some challenges that I first had getting this to work for my bike.

The company has always been responsive and the products are of high quality. Love this power assist kit! I can now ride down into Edmonds AND back up the hill, a 400 ft elevation gain in 2 miles. Still takes some effort, so a workout, but I don't have to push my bike up the hill.

I've only had the kit for a few days now, but I am blown away by the power and control that it provides. With the 48v motor, I can ascend some hills with no pedaling, and very steep hills (40 degree incline or more) with some pedaling. It was absolutely worth it.

I purchased this kit about six months ago. I purchased a 36V 250 watt kit with a 700c wheel for my Trek hybrid. I purchased it because I wanted an assist from the motor for the difficult hills I have to ride to get home. It was the perfect solution. As I approach a hill I simply push the button and the hill disappears. I have ridden up to 25 miles but I try to use the battery only as-needed because I want the workout too. The only thing I wish I could get would be a battery charge indicator because I get "range anxiety" on longer rides. I researched electric bicycle options for easily three months before I settled on this solution and the product has exceeded my expectations and remains trouble-free after six months of almost daily riding.
