Electric Bike Conversion Kits are prepackaged sets of components designed to fit on a normal bike and convert it into an Electric Bike. These kits make it easier for end-users to find compatible, functioning parts and purchase them all together. A kit can range from a complete system that includes all the small parts you need, to DIY kits that include only a few parts and leave the rest up to the user.

One of the only full suspension electric cargo bikes I’ve tested, the suspension is adjustable and provides a lot of comfort to you and your cargo when paired with the premium Schwalbe tires. Excellent safety features including integrated LED lights, the headlight points where you steer and has……
ACCURACY IS OUR TOP PRIORITY. Our electric bicycles are built in the USA from global components to meet or exceed industry standards with industry leading accuracy for all our specifications. We test for rated efficiency versus max peak power. This ensures that the electric bicycle you buy, performs exactly how you would expect in battery life, speed, distance and power.
Ideally, I would buy a battery with the same type of connection and just carry the spare one unconnected and swap them over but I don’t seem to be able to find the type of battery case for sale anywhere. It’s a quick release bottle type battery that has two sprung terminals about half inch in diameter that contact with two large terminals on what I think must be the motor controller integrated into the bottom of the bottle mounting bracket.

I have been looking up materials and researching where to buy them for my battery pack. I’ve come to the exact conclusions (and almost the exact same materials) that you write about in this great article. Too bad i didn’t find it earlier… Doh!
The Xing mid drive construction is similar to the famous Cyclone, with a planetary geared reduction between the motor and the output sprocket. The motor looks like it might be the 400W MAC/Kollmorgen used by Currie, and it is rated at 370W by Xing at 24V (which would equal a 16A controller) and the battery is listed as a Lithium-Ion with 15-Ah.
I have an old 12V DC Brush Motor which its consumption is around the 12A, 13 A and I built a Battery pack, with two groups of batteries, (4S6P)+(4S6P), which makes a total pack with 14,8V 30A. To make this battery pack I used 18650 Samsung Cells 2600 mAh.
Accessorizing your bike or scooter can be a lot more fun than searching for replacement parts, because now instead of talking about something you need, we’re dealing with something you might just want. And many riders are going to want things like front and rear battery-powered lights, bicycle baskets for either the front (for groceries or small pets) or the back (for cargo for longer trips), trunk bags and handlebar bags, upgraded fenders for foul weather or simply a neater look, mirrors, upgraded and more comfortable seats, protective gear and a whole lot more.
Torque arms are to provide reinforcement for your bicycle frame, when using an electric hub motor. They are a MUST for almost any electric bicycle conversion, but especially for front or rear applications.
Hi Pip! In addition to size and weight constraints battery size and design is also a bit factor for traveling with an ebike because flights are very restrictive with Lithium-ion cells. One bike that comes to mind that might fit your needs is the Brompton ebike conversion from NYCeWheels. The bike itself is solid and their custom bag systems and motor choice are all very well thought out. The downside is that I believe this only offers throttle mode… and is pretty expensive. Another approach might be to purchase a bike on location in each country then sell before you leave, or even explore renting? Here’s a guide to flying with batteries from the US FAA (the rules might even be more restrictive for international). I’d love to hear what you come up with and what you decide on… There are portable kits that you can use with normal bicycles for that boost if you’re open to something a bit different. Check out the ShareRoller here, they have a newer design now that’s lighter and quieter.
This drive is new and is VERY similar to the recently popular Bafang BBS02. This pic was taken at the April 2014 bicycle show in Shanghai, China. Pic thanks to ES member d8veh. On Alibaba, these have been seen being sold under the “BTN” label (Back To Nature). Thanks to the German pedelecforum.de member “airbox” for the link. Danke Schoen!
Now that you’ve got an understanding for what a hub motor is… let’s talk about the benefits, drawbacks and ride quality. Hub motors tend to be peaky vs. torquey meaning they operate best at medium and high speeds. This makes them zippy and satisfying no matter which gear you’re pedaling in but less efficient over a range of speeds, especially slower ones. For example, if you’re starting from rest going up a hill and try to accelerate with a hub motor, it may struggle and even shut itself off. Here’s a short video I shot with a smaller 250 watt hub motor climbing a hill to demonstrate this.
To develop a new hub motor would cost over $500,000 in tooling costs for a factory in China. Thats why even though there are many hub motors around for E-bikes, most are the same types or clones of existing types. Here is a list of known acceptable qualty hub motors available as of March 2012.
Having built a 13s4p battery to the best of my ability and hooked it up to my 48V 1000W ebike conversion kit…. the lights on the throttle turned on and the wheel spun! Initially I thought the project was a success but after mounting the battery and controller onto the bike and taking the bike for a test spin I ran into a major problem.
Installing an electric bike kit is easy to do, can be done in just an hour or so and can last for many years if done right initially. Deciding on the right electric bike conversion kit, the one that suits your riding style and your bike best, is the most important decision you’ll make during this process. Good news… you’ve come to the right place!
So hub motors take the place of regular light weight hubs, connecting the wheel to the bicycle axle. As they receive electricity and spin, the bike is propelled forward and some of this energy is exerted into the frame at the dropouts. Usually the sturdiest place to mount a hub motor is in the rear wheel because these dropouts are reinforced and have four legs connecting them to the rest of the frame instead of just two on the front fork. These four arms consist of two seat stays and two chain stays.

A lithium battery is the heart of any electric bicycle. Your motor is useless without all http://electrichuntingbikes.com that energy stored in your battery. Unfortunately though, a good ebike battery is often the hardest part to come by – and the most expensive. With a limited number of electric bicycle battery suppliers and a myriad of different factors including size, weight, capacity, voltage, and discharge rates, finding the exact battery you are looking for can be challenging and lead to unwanted compromises.
Case Material：ABS Aluminium alloy. DuraB/Landcrossers Fish E-Bike Battery. Battery Type: Fish Lithium-ion. Fuse Installation position: Inside on the PCB. Fuse Diameter(mm): 5. Fuse Length(mm): 30. Component: Li(NiCoMn)O2.
Here is a picture of what the inside of one gearless, direct drive hub motor looks like. You can see the magnets glued around the outside of the cylinder and just inside from them are electromagnets (made from metal and copper wiring) that create repelling force to drive the motor forward without the use of gears:
With the Multimeter I see that is everything OK, I see the voltage of the 4S in B+ and P-, but when I connect the motor nothing happens, the voltage goes to zero. At this moment I want to discharge the batteries and I connect B- to B+ and is working OK, of course.
