Kits to Convert Bikes to Electric Betterbikes™
Second step in creating a Betterbike™ is choosing 1 or more motors. Note that recumbents can be fitted with a variety of mid-drive motor or a hub-drive motor kits.

Hub motor kits power the bike using a hub motor built into the bicycle wheel.
- BMC
now offers a light (9 lbs) brushless planetary gear hub motor kit. This hub is reliable, quiet, efficient and affordable.
7 NEW BMC motor models are now available for 2009!
Rear BMC V1-T 400W High-Torque (the original rear, only improved)
Front BMC V1-T 400W High-Torque (the original front, only improved)
Front BMC V1-S 400W High-Speed wind (new)
Rear BMC V2-T 600W High-Torque (new)
Rear BMC V2-S 600W High-Speed (new)
Front BMC V2-S 600W High-Speed (new)
Rear BMC V3-S 1000W High-Speed (really new)
The original BMC V1 motor has been improved, and now there is a choice of windings for torque or speed.
The 400W spec is the continuous warranteed rating. It can actually handled bursts of up to 1200W peak.
In addition the powerful BMC V2 600W is offered, also with windings for torque or speed.
BMC V2 can easily handle bursts of 1500W peak (and beyond) and can therefore handle Crystalyte Controllers 36V-72V 35A.
We have not run into the power limit yet with controllers we tested, although there surely is one.
Just in! A really powerful BMC V3 1000W has just been realease, this one is currently rear with maximizing speed.
BMC V3 can easily handle bursts of 2500W peak (and beyond) and can therefore handle high current maximizing speed even at lower voltages.
We have just received this motor so we don't know what limits it has if any, but if V2 is a guide, the V3 should have spectacular durability and performance.
Thicker axles, disc brake compatibility front and rear, total free-wheeling, light weight, and several models and windings. It is all here.
BMC offers the best price-to-performance value in the market!
We have developed a 'smart' shopping cart that will help navigate the numerous kit configuration options and automate kit purchases for online customers.
Try it out! This cart has some built-in intelligence and we will keep adding more knowledge base with continued testing and customer feedback.
It even calculates the specification, weight, price, and incompatibilities in real time,
so you can feel confident that the system you choose will work as expected.

- BionX of Canada offers well integrated, lightweight hub motor kits featuring an advanced controller, both power-on-demand and ped-elec operation, and regeneration. Prices range from $1000 - $1500 depending on choice of battery (LiPo/NiMh) and Voltage (250W+ at 24V, 350W+ at 36V).
- Heinzmann of Germany builds hub motors kits with both wattage and gearing options. Heinzmann has built electric motors for 40 years, and offers hub motor kits starting around $1000. Heinzmann hubs are efficient, lightweight, and have almost no drag when coasting.
- Crystalyte offers a series of
hub motors for both front and rear wheels in 16", 20", 24", and 26" wheel sizes. Prices range from $600 to $1100.
The Phoenix series can deliver 48V X 40A with PbA or 58V X 40A with Li-Po, both will turn
a standard mountain bike into a 25-40mph vehicle. Crystalyte also offers other hub motor kits in the 15 - 25 mph range.
NEW UPGRADE! Now the Crystalyte phoenix series comes with an insanely powerful 72V 40A controller. With this voltage even small 20" wheels can get over 40 mph. This is great news for recumbents bikes and trikes.

Quadribent™ Side-By-Side Recumbent Bicycles for Two People.
Ready to "take the lane"? The EZ-1 Quadribent™ is a recumbent vehicle consisting of parallel paired recumbent bicycles joined together side-by-side to form a recumbent quad bicycle that two people can ride together. Optional rumble seats accommodate additional riders. The Quadribent™ includes a built-in cargo platform which allows you to easily carry things with you: groceries, a picnic lunch, perhaps even your dog! [Editor's Note: Or a big battery pack for long-range riding.] Add an electric drive (e.g. Electro Cycle E-4) and you've got a scaled-down "car". Bike together for fitness, health, therapeutic exercise, sport, family fun and transportation. Learn more at http://www.blackbirdbikes.com/index.htm
