Crystalyte 404 hub motor

[stevebills]

I have obtained a Crystalyte 404 hub motor on a 26" front wheel are they any good?
I want to get speeds of 25+ mph on my hardtail bike with a range of 15 miles
Can I use 72 volts?
I have a 48 volts 15 amp Shenzhen controller that needs testing
Whats the best controller and battery to use?

Controller

Hi I can recommend the controller from Ebike ca

http://www.ebikes.ca/store/photos/C3640-NC.jpg

Standard 36 or 48 volts resistor change 60/ 72 volts 40 amps


High power mosfet,s not cheap but designed to go with the motor


Delivery by FedEx about 4 days you will have to pay vat and duty

check through the forum at endless sphere, lots of help can be found by searching through the forums.

Well worth a look is www.ebikes.ca Homepage of the revolution - they have some advice on the 400 series crystalite motors (there are a few different ones depending on the coil wiring), and the other motors too. There's a simulator to play with where there are motors you can enter, and certain batteries of voltages up to 72V. That's as well as selling controllers, wiring, etc.
If you're serious about high voltage (higher voltage = higher speed if motor can take it) check out the uprated controllers sold by Edward Lyen while at the forum. One he has at the moment - 12 FET 84-132V Infineon Programmable Brushless Controller, your motor might not handle 100V+ though. Also an 18 FET one (only one left though). He doesn't have a web site, but sells through the forum and has a good reputation- you'll need to search through to see what he has. Very knowledgeable and helpful too!

48v is more than enough on the 404 for what you need. The Lyen controllers are highly regarded on ES or you could discuss your need with E-Crazyman off EBay.
