Customer Reviews

Received my A5 in just 3 days after ordering, amazing! The bike was delivered in a well protecting huge cardboard box.Installation was a breeze. After charging the battery it was time for a little testdrive. I was struck by the stability of driving with the tiny 14″ wheels. The power of the hub motor also surprised me, cruising at 22 km/h. with my weight(120kg), little climbs or uneven surfaces, all no problem. The built quality is very good, nice welding and paintwork, quality components. The comfort of driving with front suspension, seatpost and super comfy thick saddle is also far above expectation. The bike is very complete fitted, good lighting frontrear, horn, security and i even discovered great brake lights triggered by both l/r handles. The braking power is great too. And best of all it folds easily and fits perfect in the trunk of my car (without the need of adjusting the saddle) Ready for some nice city rides! Very happy with the choice for this bike!

I’m impressed with the quality of this bike. I really like how compact the bike is. It is easy to assemble bike, perfect to fit into the car, with an great electric mode.We take it to the beach, and we had so much fun. We are also using the bike to pace my running, I run, and my husband goes on the bike.It’s a perfect gift for anyone. 5 stars, highly recommended it

I purchased the A5 because we have another DYU mini bike purchased 6 years ago that has only needed a battery replacement and has 900km on it. HOWEVER after only 20km and 3 rides the cheap bad quality plastic base mount plate under the battery is now cracked, brittle, and falling apart (see photos). I thought surely that this would be covered by the warranty but after several requests, I have been repeatedly denied and the part is not easily obtainable. I had to put sticky furniture rubber pads under the battery to afford some cushioning underneath because I have no other recourse. I looked online for the part and did not find it, nor did DYU offer to sell it to me. I will not be giving DYU my business again. Also, the metal shaft that the battery slides down on was not filed or smoothed down and had razor-sharp edges, which I filed down with my jeweler’s metal files. It was dangerously sharp. Fresh machined edges with no finishing.

Pas déçue du tout par l’engin qui tient tout à fait ses promesses. Dommage que je n’ai pu choisir la couleur! Très satisfaite du sérieux et du professionnalisme du site. Commande passée en toute sécurité et livraison rapide (moins d’une semaine). Un bémol à tout ça. Je n’ai pas la facture de mon achat. Comment l’obtenir car mon assurance me la demande?

Quality and price!! Recently purchased. my birthday present 16 august. Quality correct price, it is comfortable for now the electric mode works well. I’m testing the battery, it seems good, I have to keep testing, it’s the most important thing about the bike. “The instruction manual would improve it. There is a button that I do not understand” The packaging lacks protection and a stronger box, although the bike is fine.

Folding Electric Bike KBO Flip

We rode them on flat bike trails and on the hilly streets in the neighborhood. After 75 miles, we have had no problems. They ride well. We were new to eBikes, so it does take some getting used to the PAS functions and slightly extra weight. We were long time regular comfort bike riders. These bikes have everything it takes to get us back to regular frequent riding. Especially at the campgrounds. My old knees like this bike too.

I think this is probably the best commuter bike at this price point that you can get. this is the best bang for your money. This has a fantastic top speed and range. The range on this is amazing.

I’m a bigger guy, about 265lbs and 6’ tall and have found that the motor is more than capable of getting me up some of the steeper sections without issue. When I asked, I highly recommend the KBO Breeze as a comfortable, powerful and reliable ebike and I’m super happy riding it around town.

This brightly colored commuter ebike has got some serious power without an overbearing and massive frame like other brands. it’s a full-size bike that can deliver d decent range and good hill climbing ability and doesn’t weigh a ton.this brightly colored commuter ebike has got some serious power without an overbearing and massive frame like other brands. it’s a full-size bike that can deliver d decent range and good hill climbing ability and doesn’t weigh a ton.

I absolutely love the orange frame. I get so many compliments riding this ebike around. It really pops and the company did an amazing job with the paint. If you have been following my channel, I review products that are unique and even make my cars different than everyone else’s so I was really happy when I saw orange as an option for this electric bike.

Customer Reviews

Purchased our first two ebike for traveling and camping while entering into our retirement life style and enjoying them. We had a minor shipping issue and needed the LCD display replaced and had a new display in hand within 8 days of reporting the issue and sending some pictures. The customer service was great and easy to work with. Currently my wife and I use the bikes more as bike and occasionally use the power assist to get around. Within the next month or so we be on and beach or path riding and sure we will get more uses of the power feature. The bikes are light enough for us to fold and secure in the our pickup. So far the purchase was a good choice for us and we are looking forward to many trips together.

So far I’m enjoying this bike, weather being difficult right now but when I do ride I like it.
