A-Bike bicycle
A-Bike bicycle known as the “world’s lightest folding electric bicycle“, was due to open at “A” shape, so the designers named it the A-bike. A-bike’s original designer for the British, Mr. Clive Sinclair is also known for designing. A-bike has received several design awards in the world.
Bike kit of A-bike is a glass fiber and weighs only 5.5 kg, folded size can be reduced to 0.03 cubic meters. In addition, A-bike wheel diameter 15 cm, which gave the user can easily put into the A-bike bag to create the maximum possible.
Bike conversion kit features: light weight: only 5.5 kg.
Small size: folded in less than 0.03 cubic meters.
Speed: speed of 24 km (the average bike speed of 30 km).
Not difficult: special gear transmission, you do not need to spend more effort to ride.
To load: The maximum load of 85 body kg.
Fold faster: Open or collapse, only 10 seconds; shrink freely, without effort.
Easy to carry: You can easily bring it anywhere: home, company, car, elevator.
Cool style: so fashionable style, no matter where you are the focus.
Strong practical: not a place, picked up and left, not afraid of stolen, worry;
Carry in his hand ride bus, subway, taxi and other transport.
Original A-bike is currently no sales in China. The official website of the UK retail price of £ 199.99.
A-bike China authorized version of the product, called a-bike smart, the market price is 798 yuan. A-bike smart does not belong to category A-bike global brand, a dealer’s license is a British non-official recognition of product quality and original A-bike truly different, Mayhem UK is the only company authorized by the A-bike smart use of the trademark and sales license, and A-bike smart sales in the mainland only. Not in a genuine original sales areas, including Hong Kong and Taiwan.
Resolution:
“A-bike smart” and some domestic manufacturers more mature production technology, as are the interior of the mainland production. As the “A-bike smart” is the transportation market until the end of last year is now less than six months to do, so quality and after-sales service and keep up with some of the production technology is relatively mature continental manufacturers (eg, raw materials, production scale, production technology and improve the degree of after-sales service, etc.) but the price is higher than on the hundreds of pieces of the same quality of product.
“A-bike smart” and any other domestic manufacturer registered the name, there is no quality in the A-bike to get any increase, the price is higher than the market rate! You will want one out there for this A-bike.
A-bike from the UK’s official website issued a statement:
A-bike smart for the Chinese-made cars, with the British original a-bike at work, design, materials and mechanical properties of no relationship, known as the ‘a-bike smart’ or ‘A-smart bike’ made in China A- bike is not a genuine original A-bike, nor is Britain’s current sales of second-generation a-bike plus models.
How-to-build-a-freewheel-hub-motor-for-electric-bike-conversion-kit
These days 250w hub motor wheels are popular with European. Nearly all of hub bike motor are brushless geared. Because there are several gears inside hub. It has more powerful than 250w brushless geared motor.
Order 1 set 12″ 14″ 16″ 18″ 20″ 24″ 26″ 700c 27.5(650) 27″ 28″ 29 inch hub motor electric bike conversion kit , convert your common bike to e-bike is so easy. Directly front or rear drive your bike.
The important part is an engine -hub motor. How to build this? There are some differences with brushless freewheel hub motor.
Step 1: winding
Calculate motor power, speed RPM and confirm what type of copper wire would you use, wind copper wires by handwork or machine, each notch should be separated by insulating paper so that not shot circuit between the coil. It takes about 1 hour to done it by handwork. And should use rubberized fabric to wrap your fingers. Nipping copper wires will break your fingers.
Step 2: fix axis into motor
Put axis into rotor winding and use a key to fix axis. Use A-B glue to paste three hall sensors on hub motor rotor, put 9-pin (three pin/each hall) into PCB and use insulated wire to fix it. Put 8-pin cable inside the axis and heavy yellow, blue, green wires to connect the three copper wires(Phase A,B,C) separately. Thin red, black wires are be weld to PCB + and – .
Step 3:soak paint
After winding should soak paint in order to be insulated. Use brush to put the insulated paint on the winding and make sure be soaked everywhere. It takes about 24 hours.
Step 4:press gear into hub
Use presser to press steel 90-gear into hub. This hub with one side cover.
Step 5:fix three gears
Use retainer ring and key to fix three white nylon gears on one steel 21-gear.
Step 6:fix magnet
Fix magnet inside the hoops.
Step 7:install rotor winding into this magnet hoops.
Step 8:install there gears on the axis of this rotor winding and put inside of hub with 90-gears.
Step 9:install the other cover.
Use screw driver to tight screw nuts. Done it.
Power on battery and use bldc motor controller to drive this hub motor. If no any strange noise. It’s okay.Then according as the size of your bike to fit this geared spoke hub motor to 20″ 24″ 26″ 27.5″ 700c 27″ 28″ and 29 inch bike kit wheel.

How connect electric hub motor controller wires
Q: Now that I understand the purpose of these wires, I need to know exactly how to connect bike conversion kit wires.
1. “you could use a switch(on/off)to short pink and black”
1.1 What kind of switch? Is it included this bike kit or I have to buy it?
1.2 If I have to buy a switch, what are the characteristics of it? How do I connect pink/black wires to the switch?
1.3 If so, do I need to buy additional wires to connect pink/black to the switch? If so – what are the characteristics of it, wire resistance/diameter?
1.4 These pink/black wires are connected to a plastic connector
Do I need to buy another connector to connect my new hub motor ?
2 “use yellow and brown wires coming from the throttle to control your bike kit cruise.”
2.1 Again-how would I do that? Do I need to connect yellow/brown wires somewhere on the hub motor controller, is so – how?
2.2 Please note that these wires don’t have any kind of connector attached – am I suppose to connect them ?
3 “put the green wire to “+” and the grey to “-“, your LED on your throttle will light”
3.1 Where are the “+” and “-” you are referring to? Is it on the battery itself, or controller, or elsewhere? (for example: battery itself doesn’t seem to have open +/- sockets – other than the one used by the supplied cable)
3.2 Can I connect green/grey permanently (so that LED always shows the battery status), if so – how would I connect? Where would I connect them to exactly – controller or battery?
3.3 Again please note that green/grey wires are not attached
to any connector, just “bare” wires, so I don’t understand how can I connect them?
If you have any additional photographs and/or drawings, please share them also. If I need to buy
additional parts – please let me know what they are.
A: Don’t mistake with the positive and cathode of your bike kit battery to hub motor controller.(red and black battery wires).It doesn’t matter about making a mistake with other wires.
Don’t worry. Short any thin wires, it doesn’t burn your controller.
1.Cruise: when your motor is running, connect the pink wire to black wire(use a wire to connect pink and black wire) or you could use your brake lever to test this function. When your brake, it will cruise, when your loose your brake level, it will cancel cruise function.
2.This switch just have on/off function, you could buy other switches in your market
3.You should use a wire to connect bike conversion kit, it doesn’t matter about wire resistance / diameter, is this wire, no current.
4.You could use spare connector: yellow connect pink wire, brown connect black wire (C&Z),when your motor is running, press this red switch, your motor will cruise as the same speed.
Put the green wire to battery “+”
Put the grey wire to battery “-”
The Led will light, try it as I said, it doesn’t burn anything.
In fact, it’s very easy to do it, for example, you could use your
handle brake (two wires) to make a female connector connect any connector (white & black, pink & black)from hub motor controller.
If possible, you could use a software “e-drawing” to open our 3D about this hub motor controller.
