Wear gloves. Work gloves, mechanic gloves, welding gloves, even latex gloves – just wear something. High enough voltage can conduct on the surface of your skin, especially if you have even slightly sweaty palms. I’ve felt the tingle enough times to always wear gloves now. In fact, my pair of choice for battery work are some old pink dish gloves. They are thin and provide great dexterity while protecting me from short circuits and sparks.

The last step of wiring the BMS is to add the charge and discharge wires. The pack’s positive charge wire and discharge wire will both be soldered directly to the positive terminal of the 10th parallel group. The negative charge wire will be soldered to the C- pad on the BMS and the negative discharge wire will be soldered to the P- pad on the BMS. I also need to add one wire from the negative terminal of the first parallel group to the B- pad on the BMS.

Hi Peter! Yes, I’m definitely planning to review all or most of the Kalkhoff and Focus ebikes for 2016… I’m just not sure when exactly?! I’ve been kind of distracted with the site redesign and some new features but the reviews are starting to happen now! I’ll try to get a good shot of the sound for you once I have one in my hands for a test 😀

Controllers for brushed motors: Brushed motors are also used in e-bikes but are becoming less common due to their intrinsic lower efficiency. Controllers for brushed motors however are much simpler and cheaper due to the fact they don’t require hall sensor feedback and are typically designed to be open-loop controllers. Some controllers can handle multiple voltages.

Most of the price involved these days in building an e-bike or buying a ready to go e-bike is the size and chemistry  of the battery pack. For the consumer its important to understand  the difference between a 24V, 36V, and 48V pack. Also know what a 10-Ah pack is compared to a 5-Ah pack.

Hub motors were the first type of drive systems for bicycles to be patented and they continue to be popular today. Instead of trying to integrate a motor into the bicycle drivetrain (complimenting the gears and chain that the rider uses) hub motors stay completely separate. Electricity is run through copper wires to create electromagnets which repel traditional rare Earth magnets and create force that rotates the hub forward (and sometimes backwards). In the early days brushed motors were used because they are inexpensive and require less sophisticated control systems but the brushes wear out over time and require replacement. These days, nearly every hub motor (geared or gearless is brushess and uses direct current DC).

Hi, First of all, thanks for all the information we can find on EBR website, and a special thanks for the video reviews. I’m living in South of France, I have two baby girls of 2 and 4 and currently I have simple bike, with a Hamax seat at the rear and a Yepp seat at the front on the handle bar… so I am looking for the next bike I’ll need daily for carrying my growing girls, down and up hills, with electric assistance. I’ve seen the Yuba elMundo and the competitive RadWagon. I tried the elMundo with the girls, but there is still a strong torque and a balance limitation with the passengers weight and the high center of gravity, especially at low speed, in town when we have to stop or slow down with the traffic. The Xtracycle EdgeRunner and the Yuba Spicy Curry that lower the center of gravity with a 20 inches rear wheel seem a good, but very expensive, option. So my question is: have you planned to make some video review also about the Spicy Curry cargo bike (with a Eurobike price) which also seem really adapted for kids transportation? Regards, Pâmini

It’s full of pictures and examples to get you acclimated to the space. I’ve also done an in depth video interview about ebikes with my uncle since he has been riding one to work every day for over a year now.

Thank you for the very informative post, and it has helped a lot. I plan on building a battery pack with 20 cells with blocks of 4 in parallel, and then I am going to put those in series to make an 18.5V, 13.6A pack. Sorry if these sounds a little bit foolish, but I am not sure what kind of BMS I should be using. Would I be able to use any BMS or would there be an issue with having extra wires if the BMS can power more batteries in series?

I reached out to the company, because I’m very interested in this system. They currently only operate in Austria, Germany, and Switzerland, and the commented that they are only interested in slow growth. There is a Canadian reseller though, but I can’t find a site.

it would be applying huge amounts of force to the chain, which because of rust could become a weak point – if the chain were to snap, then the rider would be without any power whatsoever and might end up pushing his bike for 5 or10 km through soft sand while trying to get home after a long day’s fishing – I suppose he could always carry a spare chain.

When it comes to layout, there are two ways to assemble cells in straight packs (rectangular packs like I am building). I don’t know if there are industry terms for this, but I call the two methods “offset packing” and “linear packing”.

Hey, I’m about to build my 16S2P pack from 32 Samsung INR18650-25R cells bought from batterybro.com. How far apart can their voltages be when you connect the parallel packs? They seem to all be charged between 3.52V and 3.56V.

I then took my second sense wire (or your third sense wire if you have one more sense wires than parallel groups) and soldered it to the positive terminal of the second parallel group. Again, note that I’m soldering this wire to the nickel in between cells to avoid heating any cell directly.

The battery maximum power = volts x amps, so if this 36V battery can deliver 30A continuous, that means it can deliver a maximum of 1,080 watts, though I would run it conservatively at a lower power level than that in most applications.

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.

This torque arm will help prevent the motor from coming loose from the fork (front) or frame (rear) and also prevent the slotted axle from bending or breaking your dropouts. It can also be placed on the inside or outside of the frame, depending on the setup and frame of the bicycle.

  1. The Netherlands has a fleet of 18 million bicycles.[74] E-bikes have reached a market share of 10% by 2009, as e-bikes sales quadrupled from 40,000 units to 153,000 between 2006 and 2009,[75] and the electric-powered models represented 25% of the total bicycle sales revenue in that year.[74] By early 2010 one in every eight bicycles sold in the country is electric-powered despite the fact that on average an e-bike is three times more expensive than a regular bicycle.[70][75]
    E-bikes use rechargeable batteries, electric motors and some form of control. Battery systems in use include sealed lead-acid (SLA), nickel-cadmium (NiCad), nickel-metal hydride (NiMH) or lithium-ion polymer (Li-ion). Batteries vary according to the voltage, total charge capacity (amp hours), weight, the number of charging cycles before performance degrades, and ability to handle over-voltage charging conditions. The energy costs of operating e-bikes are small, but there can be considerable battery replacement costs. The lifespan of a battery pack varies depending on the type of usage. Shallow discharge/recharge cycles will help extend the overall battery life.
    Moving on to the next motor type, gearless hub motors deliver smooth, quiet performance and are often considered “bulletproof” by shops due to their simplicity. That said… I’ve heard of the glue inside that holds the magnets onto the canister or frame coming loose due to heat and excessive vibration. Gearless hub motors rely purely on electromagnets and may not include a freewheel mechanism because when the magnets are powered off there is very little friction or magnetic resistance to overcome. Motors that do not freewheel are called direct drive and this actually enables regeneration (the production of electricity based on repelling magnets inside the motor).
    I have built a few 13s lithium batteries in the past year following your instructions. Thanks. I have taken one of the batteries apart to check its condition as it is the middle of winter here in Winnipeg, Canada. Two parallel sets were out of balance with the rest of the pack. I was wondering if there is a way to use my imax b6 balance chargers to rewire the battery and keep each parallel pack in balance for sure! This way I will bypass the bms. Does this make sense?
    It’s best to try and match the cells as closely as possible based on capacity by using a lithium cell tester like this one. If you plan on using the battery you build for a high drain application, different current ratings will be more of an issue. If you have many cells in parallel and will only pull low current from each one, then different current ratings are less of an issue. It’s always best to use perfectly matched cells, though I know that’s not the cheapest option and is outside of the budget for many.
