    Best bike engine deal you can find

    Best purchase ever!!

    This is the first time I've built a motorized bicycle, and this kit had everything I needed, it works great, it is a little loud, but I don't mind, it is a strong engine, I weight 300lbs and this thing pushes me up a steep hill no problem with minimal pedaling, I ride it to work and back every day, I can do speeds of about 20mph (fast enough for me) but then again I am a big guy, I'm sure lighter people will easily zip around with this quite a bit faster.Had to tune it quite a bit but it wasn't difficult at all, I do recommend going to your local auto parts store and getting a new fuel filter and some real gas line hose ($10 total) because the filter and hose that come with this kit will probably leak like mine did, I won't take away any stars for that because the kit is simply amazing for the price as it is, minor issues are to be expected, nothing is perfect and if you are a bit handy and have common sense, its nothing you can't fix.I highly recommend this kit, its affordable, its strong, easy to assemble even for newbies (did not come with instructions and I still put it together, its pretty common sense stuff), its super fun to ride around with it, just make sure you have some good brakes on your bike please.

    Everything was there

    Took a couple of hours to install. Not to bad except putting the sprocket on that was a booger. Started up 1st try and ran welll, Much faster than I anticipated, no speedometer but going downhill im sure I was over 40mph, on level ground I would estimate 25-30 mph. It does slow down to probably 12-15 mph on the uphill. Only complaint so far is the crap gas line, it leaked form the start, so best to go buy a good gas line and some hose clamps from the beginning.

    very recommend

    I was very impressed with this kit, very well packed with insulated in the box, put it on take couple hours and have been riding it for the past weeks with no complaints. Biggest tip I have is gets lots of loctite and some rubber shims to put between the mounts and frame to reduce vibrations
