  1. I found one finally 5 Star Review

    Not knowing what to search for to find a threaded crank arm (I thought you needed an entire bottom bracket) I resorted to welding a cut up hub to my crank arm.... and of course it wobbled enough to be a problem. So I went on the hunt again and realized they do exist... and they dont cost an arm and leg. These seem to have enough threads to be spaced inward if needed. Plus they are lighter and longer than the originals. And shipped quickly w/ stickers.

    I haven't installed these new cranks yet, but they' are .going to work like a charm on my project. Can't wait to get the rest of the parts made so I can put them to use

    This was a quick bolt-on installation, fit my bike perfectly. The R/H arm has external threads that match the freewheel. You just spin the freewheel onto the crank.

    Love the new crank set. The smooth cranking with my jackshaft makes my gasbike very enjoyable ride.

    Nice cranks - machined perfectly,all the threads are bloody beautiful- the pedals & the freewheel screw on smoothly with just your fingers. I cannot find any faults with these cranks!

    Perfect for my application. The cranks fit modern pedals, not the 1/2 beach cruiser pedals or kids bike pedals. This is good. BMX pedals are cheap.

    I used a 3 speed freewheel (yes, they exist, on Amazon), and a modified front derailleur, to get ultra low gears for loaded touring. I recommend using a freewheel spacer, or filing the right crankarm a tiny bit for chain pin clearance on the 22t gear (16-19-22 freewheel). For the standard BMX freewheel of any size, or the spider and 36-48t freewheels sold here, nothing is required. Just grease the threads and install assembly.

    This product looks good on any bike, too, with wide arms, plenty of clearance on frames with standard bottom bracket lengths (if you had a triple crank, this is a direct swap). The threads were well cut on the fw mount and the pedal bores. 5/5 Will buy another.

    I have a Grubee Starfire GT-2-GGG-2 That's the Dual Start 49cc motor (Pull Start and Centrifugal Clutch). It came with a 3 piece crank arm set. Where they came up the pedal crank arm is a mystery to me. They look like big toilet flush levers or a kids tricycle pedals. Someone said they are off an exercise bike. Who knows. I went searching the Internet for something else. Prices for crank arms were all over the place $20-$200. You have to look for Unicycle parts just to find arms without sprockets.

    Since I own an SBP shift kit it dawned on me that the crank arms for it should work. I was right! They clear the pull start with about 1 1/4 inches and the centrifugal clutch with 1 1/2 inches. So for those times when I pedal the bike, like to start it, life is so much better.

    If you have that long crank, this is a great replacement for what you get with the motor kit.
