I purchased one of these kits, installed it on a cruiser style bike, and have thoroughly enjoyed riding it. Ordering was easy, this company advised they received my order, followed up with tracking information, and my kit arrived in perfect condition at the specified time.
I would highly recommend HandHeldItems for all the above reasons and I look forward to making many more purchases from this company in the future.
I'm very impressed and completely satisfied.
Better than GOOD, EXCELLENT!

I bought two of these kits for a friend and I and have assembled both of them. For what you pay this is a great deal. I would like to first say that I am very pleased with the product especially with the price. I say this because there are many expectations you may have for the product that might be unrealistic.

1. The description says that the kit fits most v framed bikes, this is true but most bikes will require drilling through the frame to mount the engine, if you don't want to drill into the frame of your bike, make sure it has 25mm tubing as only this size will fit into the mounting hardware without damaging the frame (by drilling).
2. For both of the bikes I made the exhaust did not clear the pedals and bending was required to fix the problem.
3. On one of the bikes the carburetor leaked fuel and this was fixed after reassembling the setup.
4. Of the two kits, one came with a black exaust and one with chrome, so dont expect a certain exhaust.

After these problems were solved the bikes have been running great for over 100 miles each. Basically, you are paying less than $150 for a mode of transport that gets 100+ MPG and can go 28mph, not to mention its a blast to ride. You may have to tinker with it a bit to make it work, but you cant beat that price. Enjoy.
