    I'm picking it up from the ebay seller tomorrow for a cash discount, he said it will fit onto a standar mountain bike.
     
  4. Get it (IN WRITING ON PAPER!!!) PAY With PayPal if possible, & last but not least find out the return policy is there a restocking fee do you have to pay for return shipping cost?
    Sometimes combine a restocking fee and the return shipping fee and it adds up to the actual cost of the product so it's not even worth returning if it's no good

    Which Jackshaft kit is this? I can recall reading something about there being a rip off of the Sick Bike Parts Shift Kit. ICR but I think it was said that it was flexy. Obviously that would be a huge problem if true. I wouldn't buy anything other than the genuine SBP Shift Kit, even though it is taking me forever to save up.

    problem.. I bought it and now the thing that the small cogs go on won't come off....the bearings are stuck on it.. i can slide them but when they reach the send of the pipe thing they get stuck there, i've tried to tap it off with a hammer it doesnt get off, i just need to de-attach it from the pipe..

    I'm not familiar with the cheap copy shift kit but I would guess that you need a gear puller.. Or maybe not as it's the bearings not sprockets.. Hmm. No instructions? :/

    Fixed, but the top bracket that holds the motor in place is impossible to get screws in...

    That ebay seller stole a copyrighted picture (blue bike) from us. Can you take a picture or two of his "instruction manual"?

    This obviously is an inferior copy of our original 2007 design. For the same price in the USA you can get out current model. Thanks.

    From what I've seen is you make the best (and only in my opinion) shift kit.

    I didn't know anyone else made a shift kit

    Chinese knock offs. For the same price as the real thing. Leaves out certain parts, junky and frankly not successful. Anyway I contacted the ebay seller and he removed the picture stolen from us. Thanks.

    My opinion is that you get the Heavy Duty SickBikeParts shift kit, and upgrade it with the Ultra Heavy Duty "twin row" freewheel bearing, as well as the optional left hand side and right hand side chain tensioners, because it will give you the proven reliability to do this:

    If you're upgrading the freewheel to the UHD straight away anyway, why start with the HD kit and not just the standard one?

    Either way, we can for the cost difference, upgrade either kit, but the HD kit does come with a BB cartridge, vs just the spindle for the standard kit. Mixing and matching isn't a problem for us as we can invoice separately. Thanks!

    At the risk of sounding dumb, is the UHD freewheels increase in strength enough to warrant replacing my current HD free wheel? I ask this because my bike has your HD kit, I have another HD kit for my next build, and a extra HD free wheel because the one with the kit failed at about 600 miles. I chalked it up as a fluke, and purchased the spare. If the UHD will work on my bike, and keep me from riding home with my feet held up in the air to keep my legs from being beaten to death by the pedals I'm interested. I'm getting close to the 1200 mile mark and getting a little nervous. To any others who might read this post don't get me wrong. I regard the SBP shift kit as a quality product, and have never regretted using it. I only posted this to see if I can make what I have, and what I am about to build better.

    Your HD FW failed because the cover snap ring was not in place. This is definitely a White assembly issue, not a long term reliability issue. It has occurred with several people, and regardless if new or just finished a bearing replacement, that ring needs to be fully seated. The pawls are the same on both freewheels. The difference is a double row of bearings in the UHD FW. This helps in application that side load the bearing, which is not typically an issue with the gas engines.
