TWin bIKE Powerplant 433
wanna go for a ride? drop me an e-mail: childrss@illinois.edu
I am a Twike Active (‘Active’ means inside I have two recumbent bicycles) built in 1998 in Switzerland, and imported into the US for a Portland Oregon mail-carrier project that never quite took off. I am legally a motorcycle (Trike body style) in most states, but I prefer to think of myself as a human-electric hybrid vehicle.
My first caretaker was Margaret James, who was the first person to successfully register -- get license plates on -- a Twike in the US. She drove me in and around the North Chicago/Evanston area from approximately 2004 until May, 2007.
My current caretakers are the Childress family in SouthWest Champaign. Matt works on campus, so that is why you see me there so much.
More about me can be found under the My favorite links section on the left, or by contacting Matt at childrss@uiuc.edu

FAQ’s
How fast can you go?
50-55 mph on the flat... I’ve been up to 59 mph on a slight downhill into Monticello from CU... but I’m not about speed, I’m about efficiency. I get an estimated 250-600 mpg!
How far can you go?
35-45 miles per charge, but not all at 50 mph!
Can you go by just pedaling?
Nope, Empty I tip the scales at around 600 pounds! Just like riding a one-speed bike up a hill, it’s far easier to get out and push.
So do you have to pedal?
No. Pedaling merely serves to extend the range by reducing the workload placed on the batteries (and of course pedaling burns fat). Pedal or not, it’s your choice.
Do you make electricity by pedaling?
The pedals and the motor are linked in parallel to the drive train -- much like the Prius. That means that the pedals reduce the amount of workload required of the batteries/motor, obeying the first rule of Green: Reduce. Electricity is Indirectly generated by the pedals when you use my regenerative brakes, so pedaling when braking generates electricity.
How much?
I’m not cheap. My batteries alone (NiCad) cost in the neighborhood of $6,000 dollars. The NIHM set are even more. A new Twike will run you between $27,5 and $35,000 (I’m priced in Euros). As a used vehicle, I didn’t cost that much ;-) The State of Illinois has up to $5,000 back in rebates and loan incentives for new (and used) alternatively fueled vehicles.
How could you spend that much on an in-town vehicle???
The short answer is some guys have a Harley-Davidson mid-life crisis, my current caretaker had a green-life crisis. Either way, the up-front cost is about the same, but I save money and the environment in the long run. The long answer has its own page.
Are you safe?
Safe for whom? I’m much safer for pedestrians, bicyclists or other vehicles than an H1 (2 or 3) or an Escalade. As for occupant safety, due to my seat-belts I’m one of the safest motorcycles on the road. Will you survive a crash with a bus or hummer in me? Hard to say, but you’ve got a much better chance in me than on a bicycle or motorcycle.

WANDTV’s Lisa Sparrow did some of the most accurate media coverage of the Twike so far. www.wandtv.com
Yes, that’s really me -- #433 -- in Chicago!
