RAD Cycle Products RAD Pro Zone Smooth Magnetic Resistance Bike Trainer 7 Levels Simulate Road Conditions Allows You to Work Out with Your Bike

I received this yesterday and I spent several hours putting the product together and taking it apart and putting it back together. The directions are not very good like mention in other reviews, so that was the first issue. Once I put it together, and mounted my bike into position the tire did not touch the spinner. I then took it apart and reassembled it into the other set of holes but then it was too tight on the tire, so I disassemble it again and instead of putting in the back screws witch lock the blue ramp into place (which makes my tire not fit) I wedged a piece of metal into the back whole which lifted the rollers and ramp making the tire touch the rollers. Me jimmieing this has made it work so I will keep it because I made it so it serves it's purpose.

This is a great product. For the price, I couldn't expect much more.I have a 26" mountain bike and the knobby tire makes it a bit noisy. But the actual trainer runs smoothly and does not seem to have any noise issues at all.I am very handy with tools and so I trued the product up for my Mountain bike. Originally the tire was sitting almost all the way to one edge but it did fit without any modifications. I really like the ease in setting it up and will use it a lot more!

There's a reason this is the cheapest one on this site. It doesn't go together easily at all - and when it's together it doesn't work. There's no space to get at the hex head screw at all. The blue lever thing won't stay in place. Why send a disassembled product when sending it assembled doesn't take up any more space? Doesn't fit most road and mountain bike wheels - the quick connect doesn't fit.

assembly directions weren't too exact, but once its together, it does great

This seems to be well built and really quite cheap when compared with others of similar design. It came without the resistance motor but the vendor supplied this item without question at no expense to me and has been great about responding. However be aware that this unit does not work with a 26 " mountain bike though it is advertised to do so and even though I have a smooth tread street tire on the bike. I had to change the back tire on the bike to a road bike tire to allow enough clearance to make it work. I am using it tonight for the first time so I've only tried it briefly. It seems to provide plenty of resistance and will require some trial and error to get it dialed in. Lastly the directions for assembly and use are worthless and if I wasn't mechanically inclined I'm not sure I could have figured it out.In summary if you are looking for an inexpensive resistance frame for a budget price then this one is solidly built and seems OK. Pay close attention to the pictures and assemble the frame entirely before mounting the bike. Use of a road tire is a must.

A few short comings; the skewer support ends are grossly misaligned and the magnetic dial selector plastic case clamp hinge broke as it was being attached to the bicycle's handlebar. Also, the roller offers very little grip. On the plus side; the low price and is easy to assemble together.

A very well made trainer. That is if you can get it together. The Chinese to English instructions are some of the worst. If the pictures were better, it wouldn't be so bad, but bad "Chinglish" and bad pictures make for some real assembly fun. If you search the reviews, you'll find the company has some better online instructions with better pictures. The 7 different speeds don't seem to do all that much between them. I even played around with the adjustment on the cable end to see if that would help. And once again the instructions were of no help.

Im working my ass of now, on the bicycle
