Posted by on October 18, 2022 Comments Off on question about 1500W rear spoke hub motor – electric bike motor – Spline Cassette

Hi I am interested in 48V / 52V 1500W rear spoke hub motor – electric bike motor – Spline Cassette.Please can you tell me if this is the fastest 1500 you sell.I would like this in a 26 inch MTX rim if possible.
 
I require high speed over torque as I am not a heavy rider. This must be laced to a very high standard and run true.
 
Will this take a 9 speed cassette. Can you declare low value so I get no customs charge
 
I want thus shipping to UK as soon as possible.

Please can you use the temp sensor that is compatible with the cycle analyst v3
When will this item ship and how long to reach UK.
I am ready to make the order please tell me how to make the order.

We don’t have the cycle analyst v3 
So we are not sure.
 
We have two kinds of temp sensor
KTY 84 -130
NTC -10K
 
Many of our customers use KTY 84-130 or NTC-10K to compatible with the cycle analyst v3
 
This motor takes about 1-2 days to make.
It takes about 7-10 days to ship. (Because of Covid-19, the shipping cost is expensive,but slow)
