Oxford Gearbox 250W 24v electric bike Kit 0-30mph 5sec on eBay (end time 11-Nov-09 17:36:22 GMT)
The Fastest and Safest Quality Electric Bicycle Kit in the World
...
All our products have UK-grade built quality components, industrially assembled by Engineers this kit got us our distinction. Marketing it is the easy part, as most hub motors are left standing in the face of a fully geared electric bicycle, our kit has been Safety Approved by the British Board and is tougher and more resilient to wear and tear than all other kits based on 1-year guaranteed Shimano, AMC, and Bmx freewheel assembled components, the motors are manufactured to Advanced D.C. standards and have been dura-tested, but most of all, all we aim to help the British public safely commute.
The video above shows the speedy performance of the kit (30mph) we aimed to achieve at 250watts. I'm 16 stone and unlike all the other kits I'd tried this propelled me up a steep gradient faster than I could have pedalled, but then the 900watt kit accelerates to 50mph (scary speed) and that was only at 36volts...(optional 48v battery pack available) That is what you should expect from our Kits. amongst other forms of support, we offer tutorial videos showing the installation method from start to finish.
This is a listing for the 250watt 30mph Max (30mph cruise) Kit. for our 900watt 50mph kit please view our other items.
Our Gearboxed motors are superior to 1500 Watt Hub motors in that:
1. 250watts is perfectly Legal in the UK, while 1500watt hub motors are Illegal everywhere (our other kits can be marked 250watt/24v)
2.Gearbox Bicycle Kits are UK-based and are supported
3. 250watt Gearboxed models last for 10 years and are dura-tested to high-tensile strain
4. if You weigh above 12 stone then we recommend this kit as it is nippy and accelerates very quickly
This kit is very practical in that it enables you to change through your gearing and gain power on either the flats or inclines.
Pictured above is my Mountain Bike with the 250w kit and 3 x SLA 9AH (range: 40miles,cruise:30mph). This kit is LEGAL as it is a 250watt, under 40 kilogram, 15mph, with pedals, electrical bicycle, our sales are reflected in our high feedback rating and we aim to help all our customers achieve the most they can out of cycling.
Having assembled this kit together and placed it under 48 hour dura-stress-cycle testing to ensure it conforms to the ECA standard it is a quality product that offers the highest levels of safety to reduce the rising fuel costs, global warming, but most importantly this kit pays for itself in fuel costs alone within 4 months. The kit is great fun to use for the whole family, if you are a family man who wants to save money then this kit is the right choice because it is built from the highest pre-fabricated and lathed materials in the UK
You CAN use this kit on cycle lanes provided you do not exceed 15mph on the road, cruising speed is around 30mph without pedal assist. To make things clear, this is as fast as it gets with pedal-assist electric bicycles, the kit is marked 24v 250watt, however Linked to your chain-drive the power output of the motor is multiplied by a ratio of 2:2:18 equalling 900 to 2300 watts on the smallest and biggest gears respectively, the kit is also upgradeable to any voltage up to 48volts, ideally it performs best at 48volts.
Battery packs are available and are £43 for 36v 27amps, or £60 for 48v 36ah (please ask for more information). We advise you to wear a helmet, get insured, and not break the speed limit or any laws.
By using a standard bicycle's gearing this kit can climb steep 45% hills, accelerate faster than some cars uphill and is most likely the best quality and fastest electric bicycle Kit you've ever seen.
If you live in London then there is the benefit of avoiding congestion charges and Traffic.
We also offer the bicycles ready-made at a higher price in mountain Bike (£860) / Beach Cruiser (£742) or Townie Frames (feel free to contact us for more information at

"The Kit has replaced the Car Completely! I never thought I'd get so much out of it, I never believed in cars anyway, my wife loves it, it gets the groceries, it gets me to work 20 miles there and back, who needs cars?!?Kim Martin"
"Steve Bowers states: that it is the most practical fun I have ever had on a bicycle, it's my car alternative when I don't feel like driving"
What it is:
250 Watt 24V Brushless Electric Bike Kit 3 Chainwheel System That Uses the Rear Gears to propel your Bicycle forward (and increases power output)
are you:
Tired of being stuck in morning traffic?
Sick of arriving late and tired to University Lectures?
TIRED of spending £30-£50 on weekly rising fuel costs?
Do you Need an alternative to your car but have a hill to climb / or get tired of pedalling? do you need something that will help you get fit without having to climb up those steep hills?
If you want to Reduce your short travel costs, or just get fit, then this kit is the thing for you.
When we conducted our Preliminary Market research and asked around Oxford we wondered who could afford a car anyway?
The main aim of the kit was primarily to ease the setup to rival the installation of a hub motor. It suffices to state that this kit takes 1 hour to attach to any standard bicycle(18",19",20",21" frames), it is 8 x as fast as a 1500 watt ''hub motor'' in that you can use your gears on the bicycle. The Built-in freewheel means pedals do not spin when the motor is running. You can pedal only if you want to (thanks to the (patented Freewheel Chainwheel Setup) When in pedal mode there remains no drag from the motor. steep hills can be coasted at up to 30mph cruising speeds on the flats, 15mph up 45% gradients. (The kits get noticed very often and hold their own reputation in Oxford).
A warning, from experience, to Ebayers: Do not buy cheap chinese ''1500 watt'' Hub motors that you have seen on the other pages, Those Kits come unfinished, contain technical and operational issues, they maintain no customer support, they are slow, they do not function to a reasonable standard and are genuinely unsafe. They do not climb hills satisfactorily and slow to a halt. Efficiency is another factor standing at 60% when we tested them (while our Oxford Kit is 94% efficient), the Hub motors are cheap and a waste.
The Largest Hub motor on Ebay today is rated at 1,500 Watts but by using the Oxford Kit through your bicycle's gearing you are generating in excess of 2,300Watts which will probably out-accelerate most things on wheels ( hillclimber superbike).
