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.

If you’re like me, then you like hearing and seeing how things are done, not just reading about them. That’s why I also made a video showing all the steps I took here in one single video. The battery I build in this video is not the same exact battery, but it’s similar. It’s a 24V 5.8AH battery for a small, low power ebike. But you can simply add more cells to make a higher voltage or higher capacity pack to fit your own needs. Check out the video below:

Oh, one last thing. If you have a poorly formed connector or the wires are fraying, that can increase resistance and cause a voltage drop that might trip a cutoff condition. Just another thing to check for.

I finally made it happen on BMS #3 (the unfortunate thing about AliExpress is that every dumb mistake that kills a part is another month added to the project) and the battery seems to work great, though it only has a couple miles so far.

hello sir. nice guide FOR battery pack li-ion… i will try an electric bike kit for my 26″ MTB. and buy 1000w hub motor kit. i can solve my battery problem (expensive you know) with li ion pack. i have some questions,

An electric bicycle, also known as an e-bike, powerbike or booster bike, is a bicycle with an integrated electric motor which can be used for propulsion. Many kinds of e-bikes are available worldwide, from e-bikes that only have a small motor to assist the rider’s pedal-power (i.e., pedelecs) to somewhat more powerful e-bikes which tend closer to moped-style functionality: all, however, retain the ability to be pedalled by the rider and are therefore not electric motorcycles. E-bikes use rechargeable batteries and the lighter varieties can travel up to 25 to 32 km/h (16 to 20 mph), depending on the laws of the country in which they are sold, while the more high-powered varieties can often do in excess of 45 km/h (28 mph). In some markets, such as Germany, they are gaining in popularity and taking some market share away from conventional bicycles,[1] while in others, such as China, they are replacing fossil fuel-powered mopeds and small motorcycles.[2][3]

Combining speed and style through an innovative pedal-assist motor, advanced electronics, and a sleek design, our Turbo e-bikes represents the full capabilities of the e-bike revolution. They’re capable of achieving top speeds of 45 Km/h while you pedal, so they’ll deliver near superhuman power to any rider.

In the end, I opted for a DPDT+OFF rocker switch, as using diodes introduced forward voltage drop and this interfered with charging enough for me to have second thoughts. This arrangement does require that the BMS be “flashed” to initiate it, which can be done by the charger in charging mode but for discharging, I found that shorting the B- and the P- for less than a second initiated the BMS and it then latched itself on, so I installed a reset button. If I had used a DPDT switch without an off position then I would not have needed to do this. However, when the BMS hits a low voltage group e.g. going up a steep hill, it will not automatically reset when the voltage recovers, so you need to use the reset button if you want to get the last bit out of the battery. I’m toying with latching this button when discharging, as the voltage drop knocks the controller out, so I think I’ll get a reaction like traction control, without having to manually reset the battery (which is annoying as it’s in a backpack).

Lay your nickel strip on top of the three cells, ensuring that it covers all three terminals. Turn your welder on and adjust the current to a fairly low setting (if it’s your first time using the welder). Perform a test weld by placing the battery cells and copper strip below the probes and lifting up until the welding arms raise high enough to initiate the weld.

Hi Ben! I had an opportunity to test ride an old Lee Iacocca eBike a while back and was impressed with how forward thinking the design was. I can see why you’re excited about the space, especially with all of the new products coming out, and given your lack of a driver’s license.

To shift optimally I suggest gaining speed then relaxing the force being applied to the pedals, shifting, then maintaining a gentle cadence until the chain is correctly aligned before exerting more force. This may be difficult on a pedelec system where the rider relaxes their input but the motor continues to pull hard. In this kind of situation it may be ideal to shift on a flat surface where little force is required to keep the bike moving forward. The problem here is that often shifting http://usebikeparts.com done when encountering hills or starting from rest; just as more force is required to maintain speed. Long story short, be gentle when shifting and recognize that mid-drive motors pull the same chain that you do as a rider.

I continued with all 10 sense wires, placing the last one on the positive terminal of the 10th parallel group. If you aren’t sure about which groups are which, or you get confused, use your digital voltmeter to double check the voltages of each group so you know you are connecting each wire to the correct group.

” Electric Bicycle I purchased from you guys has been outstanding. I have had it now for almost 1 year and I use it everyday to commute to work 2 miles from my home. Everyone at the office always comments on how great of a idea I had. I also bought one for my 2 son’s and one for my wife. Electric Bicycle folds up easily for transportation in my car so I can take it with me everywhere I go. ”

The battery cells have now been assembled into a larger 36V pack, but I still have to add a BMS to control the charging and discharging of the pack. The BMS monitors all of the parallel groups in the pack to safely cut off power at the end of charging, balance all the cells identically and keep the pack from being over-discharged.

Hi Kim! Great question… I’ve heard some ebike companies and shops guestimate that 180 lbs is a good cutoff when jumping from 350 to 500 or 750 watts (750 is the highest allowable in the US). I’m sure you could get away with a 350 just fine, especially if you pedal along a little to help it get started each time and ride mostly on flats. Here’s a video interview I did with an individual of similar weight who was riding a 350 watt motor for over two years and using a throttle with higher powered 48 volt batteries… you can hear some grinding when the bike starts and I believe this is based on accelerated wear and tear. I hope this helps and welcome you to share what you choose and how it works down the line. I personally appreciate the compact size and efficiency (and lower price) of 350 watt motors but most people would recommend that you aim for 500+ watt in this case.

Yamaha’s newest entry into the electric bike market shows a lot of potential. It’s no surprise: Yamaha has been building electric bike systems for more than 20 years, has millions of systems on the road, and produces nearly 300,000 units annually.

  1. There are a number of things that make Bionx unique. Bionx pioneered the introduction of torque-sensed pedal assistance by creating a drive system with a torque sensor and controller integrated into the motor. This allowed for clean and easy installation, minimized reliability issues that can result from faulty wiring, and simplified servicing. In 2010, under Magna’s direction, the sophisticated CANbus communication system was built
    In summary, the drive system you choose will impact the overall weight and weight-distribution of your electric bike. It will provide more or less efficiency for riding fast, climbing or navigating bumps and it will cost more or less depending on how customized the frame is and whether it offers regeneration and special sensors for shifting gears. I lean towards geared hub motors for affordable light weight around-town transportation, direct drive hub motors for quieter riding, increased power and regenerative braking and mid drive motors for mountain biking or lots of hill climbing.
    After writing my question, I did more research on these cells regarding overcharging and over-discharging and I see where you’re coming from regarding not having connections between the parallel cell blocks to smooth out differences between individual cells. So as a permanent installation, it’s not going to work. However, I’ve had another thought, which I’ve put at the final paragraph.
    To reach our intended voltage of 36V, we have to connect a number of 18650 cells in series. Lithium-ion battery cells are nominally rated at 3.6 or 3.7V, meaning to reach 36V nominal, we’ll need 10 cells in series. The industry abbreviation for series is ‘s’, so this pack will be known as a “10S pack” or 10 cells in series for a final pack voltage of 36V.
