3625 36V 25A 900W 26mph 21mph

If you are looking to take the pain out of your commute, or simply need some help on the hills, the Cystalyte Phoenix II 3625 hub motor system may be what you need. The Phoenix II 3625 system will bring a new life and meaning back to that old bike frame that's been sitting down in the basement all these years! For those of us either in less than perfect shape, the Phoenix II 3625 will allow you to get back in shape at your own pace. The lack of sweat and exhaustion upon your arrival to work is a much better way to start your day than being worn out before the work day starts!

4825 48V 25A 1200W 30mph 25mph

With a little more power than the Crystalyte Phoenix II 3625 system, the Phoenix II 4825 may be appropriate if you're installing the Crystalyte hub motor on a smaller wheel diameter such as 20 inch or 24 inch. Remember, the smaller the rim diameter the more torque you have, but less speed. Since an increase in voltage results in increased top speed, the added voltage of the Phoenix II 4825 is a good match for smaller wheel diameters, and for those where 25mph is fast enough! Trikes, tadpoles, and recumbents are all great vehicles for the Phoenix II 4825 System.

3640 36V 40A 1440W 32mph 28mph

Now things get interesting! The Crystalyte Phoenix II 3640 starts to light things up! You must form the same habits as you would riding around town on a motorcycle, and we also recommend DOT approved helmets for your safety. Despite its innocent appearance and light weight, the Phoenix II 3640 is a stand-alone system, meaning you do not have to pedal...ever. Unless you're trying to ride up the side of a mountain, the this system will climb about any hill without help from the rider. The Phoenix II 3640 comes with a quick battery disconnect to remove the batteries from the rack for charging if necessary.

4840 48V 40A 1920W 35mph 31mph

The famous 4840 has always been a part of our Phoenix line, but now with the amazing improvements that you've probably already read about! We have Crystalyte install sensors in all our motors so that with our 4840F revision controller they can be used as sensored OR sensorless....your choice! It also seems that with the drastic weight loss and higher reliability the Phoenix II 4840 rear motor has more speed than the original 4840 Cruiser and Brute motors! Treat the Phoenix II 4840 with respect and it may outlive your gas vehicle in mileage! Not to mention you get to part at the front door about everywhere you go! Some of our customers have systems with over 30,000 miles and counting, while one in particular is nearing 40,000 miles!

7240 72V 40A 2880W 45mph 37mph

The Crystalyte Phoenix II 7240 is the most powerful system available, and has been for years. This is for the serious commuter, thrill seeker, or one who needs to pull an awful lot of weight. It's high voltage and and current offer serious torque and speed, over 45 mph with the Cruiser and about 40 mph with the Brute! Even if you don't use the Phoenix II 7240 system at full throttle, your range will be that much greater. If you want serious power, you've got it!
