Good day. First post. Im running into a problem with a hub motor. Im a high school shop teacher and we decided to build the Silent speeder. So I ordered the plans, we cut up the frame, ordered the batteries, but I have run into a problem. All the Rear hub motors I see have 135mm dropouts. The rear dropout of the BMX we cut up is about 110mm. I understand those 135mm dropouts are for a gear sprocket assembly, thats why its wider. I cannot find a 110mm or so Rear Hub motor. So question....can I put a Front hub motor in the rear? and will it work ok? Plan B is to widen the rear stays to fit the 135mm distance. Maybe I would need to come up with some sort of spacer if I did have to use the 135mm hub. Not quite sure. Just wondering if anyone has had any experience with this issue. Really do not want to make a mistake when I order. Really want to complete this and let our school use it. Thanks in advance.
