Npr did a segment today on "Science friday" regarding e-bikes & the first thing i thought was an electric xtracycle would be cool as s*it....The above post w/ xtracycle/sidecar really blew me away. words cant describe how awesome that setup is...good job!
Yeah the rear rack is less than ideal. I have a new battery on route for this season that I plan to get into the frame so I can loosen the rear shock back up again.
I built the bike in the 90's and electrified it 2 summers back and put some (needed) new forks on it. My sla's are far from holding a full charge but they should be some fun to run 24V in my kids 12V ride-ons they've outgrown, until they're completely dead
Here's my Schwinn Cimarron 21-speed. 48V, 1000W front hubmotor, 20Ah LiFePO4 battery.
'72 Schwinn Sports Tourer, original except for seat and 116psi tires
48V 1000W black unbanded rear hubmotor kit from YXM Corp, 48V 20Ah LiFePO4 batt
'79 Schwinn Twinn Sport 10sp tandem, 47#, now 14-speed with 12/34, aero wheels
'07 Trek 7700 hybrid, 27sp, 20" frame, Conti UltraSport 700Cx28 116# tires, sweet
'04 Trek 7500 hybrid, 17.5" frame, soon to be 48V 1000W rear-hubmotor electric bike
these frame bags are great
Has a wobbly rear wheel, 08 model with 2 batteries that work for $250, I fig. if I have to get a new rim and respoke it's still a steal. Bought sight unseen, paypalled and beat over 20 people to the deal
Picked this one up for my kids (but I ride it ) and it was a steal for $120 too
I even got the matching helmet and battery holds enough charge to just get to work. Runs really strong with my 8 and 9 year old on it, 24V so hills really effect it and no pedals to help
Good cheap fun, I wish I could say that for the one above, I've had some probs and hope to have it running perfect this weekend, not touching the blue one yet.

Allen, I LOVE the bike you bought for your dad. Can you tell me a bit more about it, a link maybe?
Seriously, I would like to have a bike EXACTLY like the one you got your father. I like the battery in the rack, the basket... I looked at Estelle bikes and couldn't find one just like this one. They all have the "saddlebag" style battery. Any info on this bike would be much appreciated. Thanks, Angie
When battery is there, don't you have to raise the seat to get the battery out????
Allen may be able to point you to the best source for a bike like his father's. There is an online retailer that builds custom e-bikes, including an electrified 3-spd Biria EZBoard--http://www.oldesaltbikes.com/osbshop...=6&idproduct=3. They use the Wilderness Engergy kit with a 36V 600W hub motor, which may not be the best choice--it also only comes with a SLA battery pack, which you'd need to replace. The warranty for the electric hub system also isn't that long. However, maybe they'd be willing to customize an 8-speed Biria with a different hub motor system, if you can't find someone close to you who can customize a bike for you. Good luck.
I came across this E-Bike when I lived in Shanghai. Still makes me laugh.
i like it. keep people from steeling it as long as it works. i have one like it.
this ones a rusty girls frame with Schwinn izip parts
New guy here on the forum, this is my second post. My first was about charging the batteries.
I just built my first E bike effort. It's an EZ-Glide conversion kit built on a Wally World coaster bike. It seems to work just fine for my purposes.
The coaster brakes were semi useless so I retrofitted a set of caliper brakes to the included hand levers. Big improvement!
My "Urban Electric 69er UberCommuter":
eZee 36V front hub w/29" wheel & Schwalbe Marathon Plus (from an earlier ebike build)
36V Lithium battery
26" Alexrims XDlite w/ Shimano Alfine 8spd IGH & 2" Schwalbe Big Apple (& Mr. Tuffy "brown" tire liner)
Salsa Cromoly 29" fork
ebikes.ca torque arm V3
Sugino single spd crankset
MKS EZY pedals
Avid BB7 calipers. The rotors are 180 front. (stock eZee disc), Shimano 160 rear.
Avid SD7 brake levers
Nice & wide Truvativ Hussefelt bar
generic adjustable stem
Cygolite Dual Cross Pro lithium headlamp
SKS Chainboard chain guard
Fizer rear rack (my original rack suffered a catastrophic failure)
full fenders front and rear
etc., etc., etc...
A BionX equipped Tidalforce frame is currently at 95% completion. Similar set up. Pics soon!

That is exactly where the frames came from.

Since I'm chronically underemployed, I have time to play with different ideas for practical electric bikes.
This is my latest....kind of a cargo bike. It's had over 200lbs on the back rack, and was still very stable riding.
I'm running a 48 volt, 11 amp hour pack made out of DeWalt A123 LiFePo4 batteries, and a chrystalite 5403 hub. In the last few days, I've put on almost 80 miles, with the longest run at 10 miles before charging. As near as I can estimate, it looks like I can expect a possible 20 mile range on the pack. The handling is quick and light, and the ride, with it's front and rear suspension, is superb....even sitting in the very ergonomic hard plastic ABS racing seat.

I just finished making this:
It uses NiMH batteries from a junked Ford Escape hybrid, so that's one less SUV on the roads :-)
Both the bike and the trailer fold and will fit easily in the trunk of a car or can be packed for air travel. They are my ninja public transport machines and are bus and train friendly. :-)
