ZIZZO FOLDING BICYCLE INDOOR TRAINER with FRONT WHEEL RISER BLOCK - FITS 20-INCH WHEEL BIKES ONLY - NO EBIKE

Caveat: if your bike's rear hub has a quick release, it may not attach perfectly and stay perfectly vertical.Overall a great product. I have a 20" Origami Bull folding bike and the rear spindle attached fairly easily to the bracket. On the left side, the Bull's rear hub quick release slightly interfered with the fit on the bike. It attached solidly nonetheless. There is a 1-2 degree tilt to the right side. Turning the handlebars slightly while using the stationary bracket keeps the bike close to perfectly vertical.Shipped by Zizzo and arrived on time. It was packaged well, constructed well, and has no visible defects. The weight it can bear is important--there are a bunch of knock-off rear wheel brackets of similar design on Amazon. none of them are rated for nearly as much weight as this. My weight plus the bike is 275-280lbs.

Even though I read all the bad reviews first and felt very nervous about purchasing this bike stand for my Dahone Mariner D8 folding bike, I am glad I did! This bike stand is awesome, easy to setup, very adjustable, and I can quickly attach my bike to it, or remove bike just as easily. One thing to note though I do not attach the gear setting to my handlebar since I just use the gear changer on my bike to adjust the resistance instead. This is a wonderful device, which I have no problems with after 2 months.

Perfect for my son’s training and works great! Awesome BMX racing training tool.

This is seriously the best fitness product I have bought on Amazon. Personal trainers told me I had to reach a Target Heat Rate for weight loss but many bikes I bought never got me there once. This one works up a gentle sweat and gets you to Target Heart Rate without pain. I bought cheap bike trainers that were super loud before but this one is much more quiet. Because it works on a small folding bike it takes up much less room in my bedroom than the cheap trainer on the cheap bike. The Zizzo folding bike is great for smooth park rides as I don't need an expensive bike rack to put it in my car. If it is raining I can also do fitness in doors. I now have brand loyalty to this product line as it has worked far better than most gyms I have been to, and I have lost 10 pounds in one month going vegetarian and using the Zizzo magnetic trainer. The Zizzo folding bike trainer is the best product made by breathing humans for fitness.

I live in northern Wisconsin and the winters here can get quite harsh. With this trainer I can ride in the comfort of my home and watch TV. It is surprisingly stable.

I raised the bike handle bars up high. Now when I ride as exercise bike my back doesn’t hurt. My arms y legs are firmer and I use my bike several times a week. Start slow and work up repetitions gradually! This devise makes it so easy!,,

What a wonder this tool is. Works exactly as stated. I can ride my bike every day now, no matter what the weather.

This works well with my 6 year old son's 20" Trek bicycle. My only issue is with the tensino adjustment screw. The way this is designed, the screw handle itself will stick into your floor on all but the smallest wheel sizes. On a 20" bike wheel (about as small as I'd go with this) it is simply too long to clear the back of the base, so instead of the trainer resting on the rear uprights it rests on the screw handle. This bends the screw and sends the handle into your floors, so be leary of this if you have hardwood.
