I ordered the 48v 1500W electric bike kit<\/strong><\/a>, with cassette.
\nI have problems with the cassette, the cassette is wider than where the dropouts sit around the axle.
\nSo the hub motor<\/strong><\/a> wheel with the cassette on is wider than 135mm.
\nMy bike frame is 135mm, and the website said it would fit on a 135mm frame.
\nWhen the cassette is on the hub motor wheel and i put the electric bike motor<\/strong><\/a> wheel on the bike, the frame grinds against the cassette when I tighten the electric bike motor wheel.
\nI have made it work using spacers so it spins freely, but the wheel is offset to one side now and i think my frame is spread wider. It is an aluminium frame.
\nAlso the website said max 7 speed gear, but the cassette is for a 9 speed gear, which is also mounted now, is it suppose to be able to take a 9 speed gear, or is that an accident?
\nAny advice on what to do?
\nAlso, any advice on mounting the torque arms? My frame is aluminium.<\/p>\n

Steel is okay.But Aluminium is not good to make it larger. We worry if make aluminium frame to larger will break frame.
\nWe recommend use 7 speed or 6 speed or single speed.. <\/p>\n
