Electric Mid-Drive Units and Frame Adapters
The Electric Mid-Drive Unit that we manufacture is our flagship product. Attach one to your recumbent bike and you will instantly have fast, comfortable, pollution free, and affordable transportation. And you'll have more fun than you can possibly imagine.
To simplify ordering, we've separated out the different components that make up our Electric Mid-Drive. Rather than have dozens of different variants, several for each bike, we now just sell the basic EMD Unit and a series of what we call Frame Adapters that customize the unit for different bikes. All you need to order is the Electric Mid Drive Unit, a frame adapter for your particular bike or trike, and a battery system.
If you're a homebuilder, have talked to us about what it takes to make your own frame adapter, and are putting together your own battery system, then the Electric Mid-Drive Unit is all you need.

Mid-freewheel allows motor to drive bike while pedals are stationary, if desired.

Order this unit now and, if you choose, exchange your BMC controller for the new EcoSpeed digital controller when it is available in spring 2009. Your only cost will be the price difference, if any.

Frame Adapters customize an EMD Unit to fit a particular recumbent bike. A Frame Adapter is not just mounting brackets but rather a carefully engineered solution that adapts the EMD to a particular bike. The Frame adapter alters the appearance of the EMD to match the bike, contains custom CNC machined mounting pieces, and, where necessary, parts to route the chain line around obstacles on the bicycle frame. Frame adapters also include all instructions needed to install an EMD Unit on a particular bike.
BIKE E RX/FX

EMD1-FA$315
BIKE E AT/CT
Requires drilling 4 holes on underside of frame, drill template included, for attaching unit. Holes do not affect frame strength and are not visible if unit is later removed. The long frames of the CT and AT are good for taller riders and have plenty of room for batteries behind the seat.

Burley Koosah, Nasoke, Spider, Jett Creek, and Sandpoint
Unit clamps below seat using EcoSpeed designed "quarter clamps". These only wrap 1/4 of the way around the frame tube so as not to interfere with cable routing or seat travel.

EMD11-FA$219
Easy Racers Tour Easy and Gold Rush, Clamp On Mount
Clamps onto the Tour Easy or Gold Rush Replica frames. Has a front chain tensioner to allow continued use of front rings. The TE and GRR are some of the fastest electric conversions we've made. Add a fairing and tail sock and really fly. The need for six clamps on the lightweight Easy Racers tubes makes this frame adapter expensive. Also, because of the many small variations in TE and GRR frames over the years, you may have to do minor modifications to your frame to get this unit to fit. If you're buying a new TE or GRR, consider ordering the version with tabs welded on at the factory to fit our assist.

These are fast, moderately priced recumbents suitable for touring or commuting.
