    grubee non freewheel HD hub?

    HI, I have not had personal experience w/ the Grubee hubs but I have heard that they are fairly beefy (although somewhat heavy). We have made plenty of sprockets for Grubee's freewheel and non freewheel hubs. Andrew

    Front Disc Brake Mounting Question- Schwinn Cruiser

    HI, I would guess that the spokes should last as long as they do on the rear of a driven sprocket ? ..... I don't have a good guess as to how much stress the spokes gets from a hard acceleration using engine (or electric motor for that matter) VS braking force. The customer that...

    Front Disc Brake Mounting Question- Schwinn Cruiser

    Hi, While I don't necessarily recommend using a Top Hat to "make" a disc drake hub up front here is how it would be done.... First, take a Top Hat Sprocket Adapter and mount the disc rotor to the top of the Top Hat....Without a disc brake hub to screw into you will need to use the appropriate...

    Band brake to disc??

    HI, There is a clamp on adapter of sorts to accomplish the above but it is a 2 step process.... First, a person would need a Manic Mechanic or Pirate Cycles hub adapter (or similar type adapter). Next, a Sombrero Adapter (like a Top Hat Sprocket adapter only bigger) would be bolted to...

    Front Disc Brake Mounting Question- Schwinn Cruiser

    HI, The two kits in the links you listed look as though the wheel hub itself needs to have the 6 disc brake mounting holes for the rotor to attach to...beyond that the caliper mounting is fairly straight forward through the parts provided in the respective kits. Assuming your cruiser bike...

    HP 36T Sprocket Disc Brake Hub Holes ?

    HI, More than likely the 6 small holes are for the 6 hole disc brake mount.....(typically the center bore on a factory motorized bike sprocket is about 1.48 inches in diameter and the 6 holes for a disc brake mount typically is VERY close the the edge of the center bore as in your pic). Andrew

    Going racing on the cheap. $500 racers, based off of motored bicycles.

    HI, In some forms of spec racing the winning bike (or whatever is being raced at the time) can be bought by other competitors for a certain dollar pre determined dollar amount after the race. THAT helps keep racers "honest"....After all you wouldn't intentionally spend $1000 in "secret" hop...

    biggest sprocket?

    HI, While we have not (yet) done one, we can go as high as 124T I believe..... FWIW the largest sprocket we have made for motorized bike use is 80 T (approx 13" in diameter). Hope this helps you....I say go for the 124T !!! ;-) Andrew

    Disc brake mounting, how to???

    Hi Guys, I think the idea of a hub adapter to make a non disc brake hub, disc brake capable can be done BUT it may not be the most cost effective / best solution. Basically, for front wheel application, you would need to have one of the hub adapters to grip the front hub and then a second...

    Ebay disc coversion kit??

    HI, I like the concept of being able to add a disc brake to any bike. However, I did read somewhere though that adding a front disc brake to a bike that was not originally designed for a disc brake can be potentially dangerous because the front fork may not be strong enough to handle the...

    Is a motorized bicycle just a bike when on the sidewalk?

    Re: Is a M-bike just a bike when on the sidewalk? HI, If in your area they allow you to ride a m-bike on the side walk just as a pedestrian would walk on a sidewalk, I would assume (by extension) that you should be able to cross in a crosswalk to the other side just as a pedestrian would...
