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.
