Q:Please send me a quote for this 20 inch 48 V 52V 1500 Watt rear hub motor<\/a> laced to a 20 inch double wall rim with 1.75 inch tyre.
\nfew questions:
\n-what is the overall diamater ( 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 bike 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 escooter 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 Crystalyte Controller.
\nIs there a wire for the hub motor temperature sensor. <\/p>\n

thanks for assisting with my inquiry. <\/p>\n

A:Please click below site.This bike 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:Both of them are suitable for the hub motor.
\nThat depends on your controller & LCD reads which temp, NTC-10K or KTY84-130<\/p>\n

Q:I have a Crystalyte 48V Controller from China and my display is a Cycle Analyst V3 from Grin Technologies in Canada.<\/p>\n

which temperature sensor and wire should be selected.
\nwhat is the maximum temperature degree Celsius the hub motor can operate to without damage or burn out.
\nOur weather is very hot in Summer season and a lot of my customers have burned out their hub motors because of high temperature when riding up hills. <\/p>\n","protected":false},"excerpt":{"rendered":"
