Shift Kit-the ultimate in shifting technology
MADE IN THE USA
$40 ADDITIONAL - UHD FREEWHEEL SHIFTER KIT!!!! EXACTLY THE SAME AS OUR HD SHIFTER KIT, BUT WITH UHD FREEWHEEL, A $119 ITEM. .TO ORDER SELECT THE ULTRA HD Freewheel OPTION BELOW. PLEASE NOTE TO ORDER THE UHD KIT = SELECT THE OPTION BELOW.
This HD Shift Kit will fit almost any Chinese 2 Stroke and allow the user to shift gears using the bike's standard rear derailleur. This and our Standard kit are what you see in the YouTube videos. Take a look at the parts list in our installation manual to see what we supply in the standard kit.
The difference between HD and standard kit: HD kit comes with our specially designed Heavy Duty Freewheel for those more aggressive riders and engines with compression mods.
The HD Shift kit also now comes standard with the complete 131.5mm Bottom Bracket Cartridge
Note that this kit comes with typical mountain bike style crank arms and requires 9/16" pedals. If you have a one piece crank you will most likely need to purchase new pedals.
Here are links to additional information, read carefully before purchasing:
SBP also suggests a chain breaker, cartridge bottom bracket tool and crank tool to install this kit.
Do not forget to measure your seat tube and select the appropriate size.
NOTE: If you are attempting to use this kit on a "FAT TIRE" bike please contact us directly. This kit is based on it being installed onto a "standard" bicycle. Fat Tire bikes may have special needs.
PLEASE CONSIDER THE SBP EXPANSION CHAMBER AND OTHER PERFORMANCE ACCESSORIES WITH YOUR SHIFTER KIT

It shipped very fast, and the packaging was excellent. This is hands down the best engineered product I've installed on any motorized bike. The instructions are great.
The pieces in the kit are seemingly high quality, except the bottom bracket leaves a bit to be desired. Mine is not perfectly true. I clocked the drive side crank arm in every possible position and went with the truest spot.
Getting the kit to work on an engine with 8mm rear studs was a bit of a challenge as well, but can be done. First task was drilling the holes larger. No big deal. For screws, I ended up using an allen screw on one side. On the other side that is below the plate I used a bolt with a 13mm head, and cut the opening a little larger (using a standard dremel and cutoff wheel) so I could fit the back end of a wrench inside. I also had to lightly grind the spacing shims to fit between the 8mm studs.
After that, everything fit great and it was smooth sailing. I haven't tried it out yet because I'm waiting on a few unrelated parts, but I'm very excited. SBP has gained a customer for life after my experience with this shift kit. Can't say enough good things.

First off I would like to state im deployed and the shift kit was shipped here way faster than I expected. After it arrived the box was very well packaged and wrapped with plenty of tape to keep it sealed. Inside the box was a very neat individually wrapped set of parts for the kit that all look to be amazing quality. I haven’t had a chance to install it yet awaiting my zeda dio reed engine and doing the install with the new engine. At this time I would recommend this company to anyone looking for a legit jackshaft kit big shout out to sick bike parts!

I installed this shift kit on my bike. Overall I like it and I am pleased with it. It would have been nice to have a set of printed directions with it. I would buy another one of this kits if I build another bike. It made the bike way more fun to ride.
SBP: Thank you! Did you have trouble printing our pdf?

The kit came packaged in a box very well organized. Each item individually wrapped.
It took me about 2 days to install the kit. Day one was the install, day two was for testing and adjusting to make everything perfect. It works very well, at least doubled my bike speed, and now my motor has a much better mount on the bike frame (very solid). I will most likely purchase another kit for my other bike in the near future. Thank You.

I bought the new kit with the UHD FW. The kit was was great before, this thing is a tank. You need to take your time with Shifter Kits, but always worth it. SBP have done a darn good job coming up with something that fits so many bikes. I've seen the knock off kits and they are pure junk. Will be back for more!!

Super fast shipping! This is hands down the best investment I've ever made. Thank you guys so much!

First I want to thanks to SBP for their outstanding fastest shipping. My package arrived in 1 day. I'm going on vacation right now as I'm writing this review. But soon as I get back I will make a video how to install this on your bike. I use Mustang Racer from Bikeberry for all my bikes I make

First off,as always,thanks to the great staff at SBP for their great service and quick delivery time ! Now on with the review of the HD Shift Kit ... I would have to say that after building numerous motorized bikes now, that have been single speed,I am forced to wonder why I've never bolted up one of these kits sooner !! It just totally transforms what used to be a pretty cool and fun bike too ride into an unbeleivable motorized bike to ride ! All of a sudden I can climb any hill with ease and standing starts are a matter of letting out the clutch and rolling on the throttle ! No more "pedal assisted" starts ! Then you just shift yer way througfh the gears and cruise along side traffic with ease and w/out "sceaming' along side them ... way easier on the motor and a pleasure to ride !
The kit itself is very good qaulity and if your having trouble figureing it out just check out u-tube videos or give the boys a call at SBP they'll help you out. Try one you won't be disapointed !

First time it's not easy to understand as a French with no mechanical instruction but finally when it's operating and understood it's rock all the way .
Very happy with this kit.

This kit is way more than you expect. Be sure you are putting this kit on a quality bike with plenty of room. But even on a really tight fit like mine this kit is totally epic. Bike huals way more booty than just a single speed kit. Its nice to have a choice of what gearing to run. Hills no problem, Mushy ground no issue, high speed down the road? You bet. This kit really takes a skilled hand to install, but with the quick knowledgeable staff at SBP you are far from on your own. A+ great kit.

awesome product! takes time, pacience, and strong mechanical knowlege. not as easy as bolying up a motor and shortening a chain, so if you dont have a strong mechanical mind, find someone to help.

This company is the best. From their online catalogue, quick email response , super fast shipping, superb packaging, last but least the quality of their parts. If all companies were this good we would be a great nation again. I found nothing to be even the least bit out of order or needing to be of higher quality. I would guess their parts are of much higher quality than the bikes they are being installed on. At this rate I probably do this again just for the pleasure of the experience ......Eric

Well, For starters i bought the more expensive 2 stroke HD shifter kit because of the reviews i read about the cheaper regular shifter kit's Freewheel kit problems. after being bit before by cheaper deals and so many people said the freewheel was better with the HD kit, i decided it was time for 'Better Safe than Sorry' and i went with the quality one. i recieved it saturday evening and had it installed by sunday night and took it out for a test run. (I had to get some tools to install it and i didn't even use the Crankshaft that was sent. my original crankshaft was wide enough) when i put to the real test yesterday morning, the expression in my mind changed from "Wow"! to "WHOOO!" With only the engine kit i was able to reach 25- 28 MPH ind i would get home from work in 25 minutes. back then i called it the "Spec-1 upgrade"... but NOW with the shift kit i was cruising at 40 MPH and i get home in 15-20 minutes, so i now call my bike the "Spec-2 Evolution"! i've gotten so many astonished looks from people riding beside me in traffic! whenever i stopped at a traffic light at least 4 people asked me where i got the motor and shift kit. and one person even asked me if i would build one for him, so i might be buying another one from you in the near future! but anyway i totally love this kit, THANK YOU SOOOOO MUCH Sick Bike Parts!

Well I have bought two of these kits and both kits came together without to much hassle the quality is right on the money I will be doing business again and again. Thumbs up SBP

I have had the kit for about 2 months now and all I can say is awesome! There Tech support is 5 out of 5 stars! Quality of kit 5 out of 5 stars! Keep up the great work guys! I hope you will expand into more motor bike parts. I am patiently waiting on the shifter kit chain tensioner.
Posted by Stetson Rydberg on Aug 14th 2013
After two days of struggling got it installed, BEST UPGRADE EVER! I can hit 50 mph easy and climb some knarly hills. It also allows me to run a rear disc brake so I can stop with ease. Tip: read directions carefully, take your time when installing, and don't bonk the ends of the shaft or u'll have a heap trouble trying to slide the bearing and gears over them. Other then that should be a breeze to install

2 thumbs up! I originally ordered a kit from speeddemonbikes.com for a lower price and the kit was crap from shipping to install nothing worked at all total false advertising i was very frustrated. Sick bike parts definitely came through just opening the box i could already tell the difference in quality and care. definitely worth the extra buck. Im stoked on this kit and will post pics of the new build. Thanks guys i will be coming back again
Posted by Craig Wayland on Oct 23rd 2012
I am kind of confused,When exactly did this kit turn into a stamped steel piece of crap? Every video on you tube shows this beefed up kit that makes this hd kit that i received look like a toy,Quite dissappointed.
None of our parts are "stamped steel", laser cut and powder coated American made steel. The design and components have not changed since we improved the design with the one piece rear bracket in June 2010. Sometimes a products performance is more closely linked to the operator/installer than the product itself.
