\nfew questions:
\n-what is the overall diameter ( mm ) of the 20 inch rim with 1.75 inch tyre ?
\n-what is the dropout distance of the axle ( mm ) ?
\n-please send me a schematic wiring diagram of the cable wires.
\n-estimated delivery by standard sea freight to Sydney, Australia.
\n-estimated delivery time ( weeks ).<\/p>\n

A: This 20 inch BMX rear bike motor<\/a> is fit for about 110mm rear dropout. (The dia. of shaft is 14mm, 14mm screw nuts, flat is 10mm that fit for 10mm)

\nIf your tire is 20 x 1.75. When you order, tire size,choose: 20 x 1.5″ \/ 1.75″ \/ 1.95″
\nTotal size of 20 inch rim is 420mm (about 16.5″)
\nThere is one cable from motor with 3 heavy green,blue,yellow wires and 5 thin red,black,green,blue,yellow wires.
\nIt takes about 10 days to deliver in Sydney, Australia.<\/p>\n

Q: yes I think the Power Circle 20 inch rim with 1.75 inch tyre will suit my e-scooter rear frame.
\nMy rear frame dropout is 135 mm, can you replace the 110 mm axle dropout with a 135 mm axle dropout.<\/p>\n

The hub motor looks like it has a lot of torque (N. m), do you have torque arms that can fit on each side of the axle flats.
\nThis will allow me to fix the torque arms to my rear frame to stop the axle spinning backwards under hard acceleration. <\/p>\n

Do you have a wiring schematic for all the wires coming out of the hub motor so I can check which wires needs to connect to my Controller.
\nIs there a wire for the thermistor for the hub motor temperature sensor. <\/p>\n

A: please click below site.This motor is 135mm dropout.

\nWe don’t have torque arm now.
\nWe have NTC-10K and KTY84-130 two kinds of temp.Can choose one of them install into motor.Will come out a white wire.<\/p>\n

Q: What is the temperature of the two types of wire… Which one is suitable for the hub motor?<\/p>\n

A: Maybe your display can choose set and choose any one of them. Default: KTY84-130 (Most customers use this temp)
\nBut, also other customers asked us to install NTC-10K inside motor.<\/p>\n","protected":false},"excerpt":{"rendered":"
