MADE IN THE USA
This kit is designed to fit the 49 cc Honda or Huasheng engine using the Hoot or Grubee Stage 2 or 3 gear box as well as the 4G of 7G belt drive. This kit will allow the user to shift gears using the bike's standard rear derailleur.
Here are links to additional information, read carefully before purchasing:
Also note you will typically use the bottom bracket that is on your bike instead of the one included in the kit.
Do not forget to measure your seat tube and down tube and select the appropriate sizes.

Everything I've received was of great quality! With the exception of a little chip off the paint of the engine mount but that was barely visible, understandably likely damaged in shipping. I installed the engine mount and shift kit on my first bike, haven't even gotten the rear wheel built and put on yet, I was so impressed by the quality of it, I bought a second set for my second bike. Customer service was great too, I called them because I entered in the wrong measurements for my first order. They were more than happy to help! They even responded to me on a weekend evening (outside their business hour), on Thanksgiving weekend! Will definitely recommend!
smooth shifting and reliable

I enjoyed building this on my 4stroke ,it offers a lot of shifting varieties!it takes a few days of tweaking to get it smooth but it's reliable and fun!

I am a 64-year old retired mechanic, and I am very impressed with the quality and design of this product. It was fun to install on my KMB frame. I had to remove the 2-stroke pedestal mount, but other than that it fits perfectly. Make sure you buy a cassette tool, crank removal tool, and chain breaker. You will need them. I've ridden it four times with no problems or tweaks needed.

The quality of this kit is Top Tier. Everything was in its own package. The instructions made the assembly a lot easier but their were items in the instructions pictures that were not in the kit. So I don't know if the instructions need to be updated. The only thing that confused me for a bit was which bolts to use in the different sections. I figured it out but if they could be color coded or number stamped that would add the ease ability. All in all its the best kit on the market. I had a question so I called them up and they returned my call. The second kit is on its way. :) Excellent Product!

ordered my shift kit on Friday, received them on Tuesday. all looks real good. I wish you gave options on the front freewheel as I have my doubts about its lifespan. I for one would have sent you more money. can't wait to get started. thanks guys

Very high quality, well made and strong. I will definitely be a returning customer. I highly recommend this kit, and this company. Great customer service! This kit is like a dream come true compared to the basic left hand drive set-up. Well worth the cost considering all the quality components, especially the engine mount. 10/10 Would ride!

The best kit available without a doubt. Very professional.

Kit seems great. all the parts fit together with minium filing and are very ingenious. i wish the crankshaft was wider as my 4 stroke is quite wide on the frame but besides that seems great.
mad props to the team at sbp. great customer service!

I m not 100% complete with this kit, just need one more part. But I am so pleased with how all the parts went together as they should and how well it is documented on how to get this all together. Bought a complete 4 stroke gas power bike kit (Bike & engine) from Bike Berry and nothing was going right with it, not even the engine would fit the bike it came with. Saw this site and figured I would take the chance on it, I am so glad I did! The package came in and first off, it will well packaged. Opened the box and all the parts are in there own group and in there own bags, not all just dumped in to one bag of hardware like my BB kit was. Due to my bike frame I need the adapters to convert my 1 piece bottom bracket (BB) to the standard 3 piece, once that is done, I am all set. I am sure I will be posting more info one I get this going. As it is, I got to say Thank You SBP for a well put together kit with quality parts.

Just purchased this item, took it two days to receive it(AWESOME!), A night and morning to install it,
install went smoothly only problem was with the hight of the engine, nothing a little sawing didn't solve, ha-ha. Ridden my bike three times now and loving everything the 4-stroke shift kit did for my motor-biking. Thank you Sick Bike Parts.
