SUMMER 2007 UPDATE We are nearing completion of our transiton to 37 Volt systems and will be shipping kits by early August. Thanks to all of you who have been patiently waiting.

Be sure and check out our new lower prices on most kits. Lithium battery prices are dropping slowly and so we are reducing our prices to reflect that. Also, as we increase our volumes, we are able to lower prices a bit from that as well. As always though, our focus in on providing the highest quality and best performance of any electric assist on the market.

We will continue to offer the 750 Watt motor is made by Powerpack. At 37 Volts, the Powerpack can supply 1000W of short term power as well as 50% more torque. The continuous rating is still 750W, but that's now very conservative.

A new 37V 600W motor with an external controller will replace our current 26 Volt 600W motor. The external controller gives better cooling and enhanced reliability such as our externally controlled Powerpack motors have, as well as 50% more torque.

The new lithium batteries are the similar in weight and capacity to our 26 Volt batteries. A 15Ah 37 Volt stores a bit more energy and gives slightly more range than our 20Ah 26 Volt. The 20Ah 37 Volt has the same stored energy as our previous 30Ah, 26 Volt. The higher voltage allows our motors to produce more torque and power for better performance. Efficiency stays the same so range is not affected.

We now have kits for almost 20 recumbent models with more coming.

Our kits come complete with a pre-assembled Electric Mid-Drive unit, mounting hardware, wiring, battery, and charger. You only need a few hand tools (and a drill for some models). Clear instructions make assembly easy for do-it-yourselfers or your local bike dealer.




Electric Mid-Drive™ Kit Versions
  
This year, because of battery and motor improvements, we will let you mix and match motors and batteries or even buy any of our kits without batteries. The last option is for those who are comfortable with electricity and wiring and want to build their own custom battery system, either to save money or to use a different kind of battery.
So now, you order the battery and motor as separate items. The battery includes everything you need -- case, fuse, switch, charger, and mounting hardware.
  
600 Watt BMC Motor with external controller.
Our efficient 600W BMC motor system upgraded to run at 37 Volts. Torque is 50% greater than last years motor while efficiency stays the same. An external controller runs cooler than internal controller motors and can be replaced separately if it ever fails. The 600W has plenty of power for whatever you want to do, whether long distance touring or climbing the steepest hills.
  
750 Watt Powerpack Motor with external controller
750 Watt motor by Powerpack. The Powerpack uses a large external controller with high current transistors to get more power out of motor only slightly larger than our 600W. The big transistors can shove more current through the motor without any danger of overheating. This means more power and more low speed torque and a motor that is the same size and weight. This is the motor to choose for ultimate, push you back in the seat, performance.
  
600 or 750 Watt Motor, Create Your Own Battery Pack Option
This option is for those who are comfortable with electrical wiring and want to experiment with setting up their own battery system, either to save money or get better performance. This kit includes either a 600W BMC or 750W Powerpack motor, throttle, and all drivetrain hardware. Does not include battery, switch, fuse, or battery mounting hardware. The motors can run at any voltage between 21 and 42 volts from any battery pack that can supply 40 Amps.
  
Battery Systems
  
Lithium Ion Polymer, 15Ah, 37 Volts
This battery contains about 550 Watt-hours of useable energy. That's 10% more than last years 20Ah, 26 Volt battery. This battery is also capable of supplying 1500 Watts of power for short bursts, 50% more than the 26 Volt. For most people, this is all the battery you will need. Typical range with either of our motors will be over 30 miles. Plenty for most commutes and for short distance touring. Weight: 10 lbs (4.5Kg)
  
Lithium Ion Polymer, 20Ah, 37 Volts
Thirty percent more energy than our 15Ah battery and able to supply 1500 Watts continuous. Typical range with either motor of over 40 miles. Used sparingly, that is, only for climbing the hills while pedaling with the motor shut down on the flats, you can stretch your range out to 100 miles or more with this battery. Enough for long distance tours. Weight: 14 lbs (6.5 Kg)

Electric Mid Drive Kit on Sun EZ-Tadpole Trike
Our Electric Mid-Drive unit on a Sun EZ-Tadpole trike. The unit tucks neatly out of site under the seat and gives the EZ-Tad a go-kart like feel. Because this is a more complicated installation that our usual kits, we are only offering these factory installed. You supply the Tad or you can buy one from us.

Electric Mid Drive Kit, RANS Stratus
Electric Mid-Drive with mounting hardware for Rans Stratus. Bolt on installation, no drilling required. Battery mounts on top of rear rack. Does not affect Pannier attachment. This kit is a bit more expensive than our usual because it requires 4 frame mounts rather than 2 and uses a special high strength idler on the chain power side. We think you'll agree it's worth it though when you turn your RANS into a rocket.

Electric Mid Drive Kit, Sun EZ-3 SX Trike
Electric Mid-Drive with mounting hardware for Sun EZ-3 SX Trike. Bolt on installation, no drilling required. Battery mounts in rear basket. The Sun EZ-3 SX with electric assist makes a wonderful powered runabout for zipping down to the local grocery store. With large basket behind the seat, you can easily carry four full grocery bags. And with 600W of power, you can haul those groceries with no effort up any hill. The SX even has an available soft top accessory for rain and sun protection. Sorry, we only have kits for the SX, not the higher performing AX and USX. Also, we don't offer our 750W motor with this trike because we feel that it gives too much performance for safe operation. The no battery option is a good deal with this trike. You can easily carry lots of lead-acid batteries behind the seat or strapped under the beefy frame for lots of low cost range and power.
EMD13-BMC600-37LP15, 15Ah Lithium Ion Polymer, 600 Watt motor $1795
EMD13-BMC600-37LP20, 20Ah Lithium Ion Polymer, 600W motor $1995

Electric Mid-Drive Kits for Out-of-Production Recumbent Bicycles
  
Electric Mid Drive Kit, Bike-E FX/RX
Electric Mid Drive Kit, Bike-E AT/CT
Electric Mid Drive Kit, Bike-E NX-5
We discontinued these kits briefly. After all, it's been 5 years since Bike E went out of business. Enough of you still seem to want them, that we've decided to continue selling them at a slightly higher price to cover the cost of making them in small numbers. The Bike E does make an amazing electric bike, especially the suspended models. And the FX is still the only full suspension recumbent mountain bike ever made. Put an electric assist on one and leave your friends on conventional mountain bikes at the bottom of the hill. You'll also leave them behind on the descent -- nothing handles the steeps like the ultra-stable FX.

Electric Mid-Drive with mounting hardware for single seat Bike-E models. Installation is bolt on for RX/FX/NX. CT and AT require drilling holes in the underside of the frame. Battery mounts transversely or inline behind seat. Use Kit EMD1 for CT/AT, EMD2 for RX/FX, EMD3 for NX-5 (the fast, disc braked super-Bike E road bike!)
