I've been riding my bike the 5 miles to and from work for the past couple of years. The only thing I don't enjoy about it is that on particularly hot mornings I can arrive to work drenched in sweat. I figured the best way to get around this was to get a motor attachment for my bike. That way in the mornings I can turn the engine on if I get too hot, and then I can get my exercise in after work on the ride home. I bought my engine at saferwholesale.com. Their inventory of bike engines was vast. So vast that I wasn't exactly sure what I should buy. I gave their customer service a call, and told them what I needed. They were very helpful, and together we decided the chrome 80cc engine kit was the best bet. It even came with the gas tank. My order arrived just before Christmas. It was exactly what I was expecting, and I had it put together, and on the bike, in just a few hours. I filled it with gas, and it started right away. I'm very happy with this transaction.
