Electric Power Kits for Bikes / Trikes / Quadracycles...
|
|
|
|
|
And now, what many of you have been waiting for...
|
|
Mid-frame mount for higher power/weight ratio. |
Electro-Cycle "E-4" mid-drive motor Kit...
Unlike motors stuck in one gear, these assist in all gears!
--24 Volt, 500 Watt, brushless, 3-phase motor, including built-in controler, planar gear speed reduction (2600 reduced 9.33:1), sensors to prevent over-heating - under-voltage, state-of charge indicators in thumb type speed regulator, brake lever power-off switches (Canada only), and everything you need to tie into the pedal gearing.

EZ3-SX by Sun Bikes with our E-4 motor system |
This kit began as an improvement over other attempts to add a mid-frame electric motor to Easy Racer recumbent bikes.
Though we now have motor mounts for most of the "Sun" EZ recumbent bikes and trikes (designed by Easy Racers) other cycles have been adapted...long frames, tandems, and 4 wheel quadracycles.

With some imagination, regular "diamond frame" bikes could be adapted so long as the chain paths are clear of obstacles... Our "MARK II" e-bike we expect to produce by next season will have a similar mid-drive arrangement, to follow the existing Charger bike product we've been distributing and supporting for several years now.
You can be assured the E-4 kits are in the same high quality category as the Charger bikes, offering the most fun-functional (and price) value possible...just as our Charger bikes have proved to be the best e-bike value on the market! Just ask our hundreds of satisfied customers, many with well over 10K miles on their bikes!
As for future products...we're presently collaborating on a number of other designs we hope to manufacture and distribute by next season... including larger non-pedal LEV's (light electric vehicles).
Sales of bikes and kits continue to fund our efforts to bring about renewable energy powered personal vehicles...hopefully to encourage shorter distance non-freeway travel while reviving a "back to Main Street USA movement" with fewer big box stores and parking lots that could eventually become beautiful parks!

Some vehicle designs and applications lend themselves to hub motor kits...
|
|
also available built into various wheel sizes. |
These "high power", Model E-1 and E-2 kits are not the normal 200 to 350W type more commonly used in Asia and Europe... They include everything you need to adapt the more traditional adult trikes, as well as other cycles.
The motors are easily adapted to most any "diamond frame" bicycles too. Ultimately we will offer our E-5 mid drive kit for regular bikes to be used in steeper terrain.

We expect to have other kits suitable for many types of vehicles:

New sealed lead with phosphoric acid battery pack options are longer lasting, less internal resistance, less harsh on the environment.
