Yes, there is at least one recumbent with power assist!
Cyclone chain drive motor with LiFePO4 battery.
And it definitely gives us uphill push!
1. In tough terrain the motor overheated quite often. I´ve machined a new motor housing out of a solid aluminium block and integrated cooling fins.
2. The freewheels are not sealed so dirt can easily get inside. By making a protective housing for the freewheel that now features shim rings no water or dust can now damage the inside.
3. The original motor mount was replaced by a new one made out of aircraft aluminium. The clamps that hold it to the frame are also made out of one solid piece.
Would love to learn more about your Cyclone motor improvements as I have a similar problem with it.
At least a few photos of the improved motor housing and freewheel will be very much appreciated.
just a quick pic of my ride
Anyone see Giants new hybrid bicycle as they call it. Im not sure the power of the front motor. but it says it can last 70 miles.
Can't beat the rugged utility and reliability of a brushless hub motor :thumb:
Here's a his and hers Schwinn Izip. I put a hard plastic trunk on mine. On my wifes I had to modify the seat to lower it for her. The seat is actually sunken into the battery compartment. It sits 32.25" off the ground.
just got this one today, it was listed on craigs list for $1000, talked the guy down to $600 and he threw in a new $65 giro helmet and a lock. rides like a dream =)

You will have to tell us how you wired the Playstation gamepads into your bike ;)
This is my L1. 36V 10AH Lithium battery, 200w geared hub motor. The whole thing including battery weighs only 23kg. It easily gets 40km range. A smooth and easy ride that looks great, too.
I got this e-bike 8 years ago. I use it for short trips around town, and on our wonderful system of bike paths. It will carry up to 40 lbs. of groceries.
The top edges of the basket are wrapped with an old inner tube. I figure the car I save may be my own.
I mounted a volt meter so I would have some warning when the battery was getting low, doesn't work well for that, and to see how the motor use effected the voltage, for which it serves well. I used a standard 15V Panel meter movement http://www.radioshack.com/product/in...entPage=search
and biased it with a 9V battery so it measures 9-24 V. To determine the actual voltage, I need to add 9 to the reading, but this is not as much trouble as one might think. I am usually worried about the drop from full anyway.
It cost me about $950 at the time. Now, you can get a similar drive system on probably a cheaper bike from WalMart for about $400. I would recommend something with a hub motor and Lithium batteries if you were to buy it today.
I still run it on SLAs, but I am planning on getting Lithium next spring.
Here it is in the grocery configuration:
I think this is the future.
Chenzhen-Sucteam 40amp/800 watt controller
Crystalyte left thumb throttle
60 psi stock semi-slick tires
22-24 easy on the flat. 30 downhill and 17-20 uphill so far.
The battery charges up to 43 volts after 10 miles, it is still at 37V!
A group of motorcycles (Harley) pulled up beside me at a stop light. I told the front guy I would race him down the street if he gave me a two-week head start. He laughed and said he would just wait for me at the gas station about a mile with a coffee if I ever got there [they were all low on gas].
Sure enough, I saw them at the station minutes later, so I couldn't resist and pulled in. True to his word, the biker had a fresh hot cup of coffee waiting when I rode in.
