Question: The review on Lightning Rods states: “This kit comes stock with two chainrings, a 32T AND a 48T.” There is no front derailleur in the picture. Does that mean it is an either or choice AND not both?

For a complete write up on LiFePO4 care and trouble shooting read our story here. LiFePO4 cells nominal voltage is generally from 3.0-to 3.2 volts, and generally, lifepo4 is a heavier and less power dense than available LiPo batteries and is not capable of as high of amperage discharge.
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.
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.
I also soldered rather than spot welded and used 1.5mm2 solid core copper between cells, pre-bent to zig-zag shapes on a jig (current is then distributed between them). Offtakes were 4mm2. Soldering technique to minimise heat on the cells was to paint the cells and the wire with flux, load the soldering iron tip with enough solder to make the joint and then, while holding the wire on with the back of a wooden pencil, touch the molten solder to the cell/wire interface and immediately remove the soldering iron tip. This worked really well in terms of soldering quality and the solder cooled very quickly indeed. I cleaned the flux off with a baby wipe and then dried it with some paper kitchen towel.

This pattern continues until we’ve got all 10 parallel groups connected. In my case, you can see that the first and last parallel groups aren’t welded on the top side of the pack. That is because they are the “ends” of the pack, or the main positive and negative terminals of the entire 36V pack.

An all-in-one solution for converting your traditional bicycle into an electric, pedal-assist bike. The Electron Wheel contains a powerful motor, smart & intuitive sensors, and an efficient battery that delivers plenty of kick to transform your ride. Just replace your existing front wheel and experience your bike in a whole new way. Really, it’s that simple.
A few years ago I bought a vintage peddle-cab for transporting my mother in law around, as she has to be on oxygen. We love it, and it is great, however, it only has one gear, so the slightest hill can be a challenge. I’m hopeful to add an electric motor to this bike this winter. Myself, my daughter and a neighborhood kid would like to build this in the back room of my house. So far I think I need a mid-drive motor and 24V lithium batteries. I looked at your recommendations here, which one would you recommend for my peddle-cab? Also I am looking for user friendly and economical. Any helpful suggestions in this project would be greatly appreciated!
So, I’ve been doing some research about eBikes (I started looking at them back when Lee Iacocca was pushing his eBike). I’ve recently become interested again and I’m looking for some advice about what kind of bike to look for.
Gearless hub motors may require a larger casing (in order to accommodate the magnets) and ultimately weigh more. This is of course a generalization because the technology has evolved to the point where some direct drive hub motors are quite small and lightweight.

Should the voltage on the charger be exact, or can it be *higher* than my battery pack? For example, I need to charge a 19.2V pack. Does my charger have to *exactly match* (or come as close to as possible to) this 19.2V, or can I use a higher voltage charger, (say, 36V)? Will the charger automatically adjust to a lower voltage, allowing a 36V charger to charge my 19.2V pack?
3. Yes, 18650’s with capacity ratings of 6000 or 8000 mAh are fake. The technology simply doesn’t exist to put that much energy in a cell that size on an economical level. In a few years we might be there, but not right now. Currently, the biggest cells are in the high 3,000 mAh range for 18650’s. 26650’s are larger cells and so those can have higher capacities, but there are many fewer options and variety of 26650 cells, so 18650’s are the common cells used in ebike packs.
My daily driver ebike has 8 cells paralled (14s8p) and it’s been working great for a long time. You can certainly make two 13s4p packs and parallel them after the fact, but don’t be afraid of making a single pack. As long as you use good quality cells, the risk of a parallel group dying is incredibly small.
This is a new one, and promises to be no better than the Li-ion battery type in terms of range, weight, or price. However, it can be molded into interesting shapes. They contain no liquid, so they don’t require the heavy protective cases that other batteries need. Also, this absence of free liquid theoretically means that they should be more stable and less vulnerable to problems caused by overcharge, damage or abuse. In general, they seem to be ideal for use in high capacity, low power applications – such as electric bikes.
When you buy a Hobby King pack, it will have a number of these large cell LiPo’s strung together like this 6 cell in-series (6S) pack. The big downsides of this pack is that it will only last you in best case maybe 300 charges and it is volatile, and susceptible to possible fire if not well managed and cared for. When using cobalt-based LiPo, it is best to use some kind of BMS, and also you should charge it in a safe location.
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.
To calculate the max amps the battery can deliver, you have to know the max amps of the cells you used. For example, Panasonic 18650pf cells can deliver 10A continuous, and I used 3 cells in series in this battery, so the battery can deliver 3 x 10A = 30A. However, you also need to know how much current the BMS can deliver. If I put a 15A continous BMS on this pack then that would be the “weakest link” so to speak, meaning the pack with the BMS could only deliver 15A continuous.
The Cyclone system is the first electric bike motor kit to work with the bike’s rear deraileur to take full advantage of your bike’s gearing system. The kit can be installed on bikes with 6 to 8 speed rear cassettes. The result is a motorized bike with great low gear power and a comfortable high-end cruising speed.
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 batteries electric scooter Check out the video below:
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.
1. The extra amperage that the battery could output isn’t wasted, it’s just sort of a safety factor. It means you aren’t stressing the battery to its limit. Also, batteries only get their full rated capacity at lower discharged. So you’re more likely to get the full capacity now than if you actually pulled 50A out of it.
One other drive system that sort of splits the difference between mid drive and hub drive is the shaft drive. It works like an automobile, positioning the motor more towards the center of the bike while driving the rear wheel with a shaft. These are not very common today, perhaps because they require extremely customized frames that are not symmetrical. While a rear wheel drive truck often has a drive shaft extending from the motor (under the hood) back to the rear wheels that is located centrally under the body, a bicycle has to use one of the chain stay arms to support the shaft. This makes it look a bit awkward and perhaps difficult to service as well.
