“lithium ion battery for electric bike bolt on electric bike motor”

Lead-acid electric bike batteries are cheap and easy to recycle. However, they are sensitive to bad treatment, and they don’t last very long. They are not a good choice if you’re serious about actually using your bike to commute.

By 1898 a rear-wheel drive electric bicycle, which used a driving belt along the outside edge of the wheel, was patented by Mathew J. Steffens. Also, the 1899 U.S. Patent 627,066 by John Schnepf depicted a rear-wheel friction “roller-wheel” style drive electric bicycle.[7] Schnepf’s invention was later re-examined and expanded in 1969 by G.A. Wood Jr. with his U.S. Patent 3,431,994. Wood’s device used 4 fractional horsepower motors; connected through a series of gears.[8]

I’ve reviewed all of the bikes you mentioned including those from Pedego (which also makes one of the Ford Ebikes), Specialized and Flux. I disagree with your local bike shop about Pedego being low quality… some of the models are a bit basic and “classic” in terms of design but the company provides good support and honors their warranty, they even did a voluntary battery recall a year or so back which was proactive and upstanding. The downside there is going to be higher price and finding a local dealer.

I’m glad you enjoyed the article. To answer your questions: I chose this type of battery instead of LiFePO4 mostly because of the cost and convenience. LiFePO4 is a bit more expensive and has fewer options for cells. These Li-ion cells are a bit less expensive and there are dozens of options with many different specifications for any power/capacity need. I’ve used and built LiFePO4 packs before and they have their own unique advantages, but for me they just don’t add up to enough.

Hey Court – I would have replied sooner but I wasn’t notified you had replied, guess I will have to check this site more often. I never thought of a front drive system before, I will check it out. From what your article said, I think I can still pedal and probably need to to go up a 8% grade. I like the idea of being able to simply detach the battery and the hub when I put it in the boat. I am going to look around for a more powerful motor as I need to get it up to closer to 28 mph if possible. Just did the ride yesterday and let me tell you the whole way I was like, “need that ebike NOW” If you have any other thoughts let me know….. Thank you, Eric

My series connections are between each group of 3 parallel cells. So all the connections that go across the short side of the pack are parallel connections, and all the connections that run along the long end of the pack are series. It doesn’t always happen that way, but the shape of this pack forced that geometry.

As an aside, the 50A-800A you’re talking about is during the output, and that’s at a very low voltage, which is the reason for the high current draw. But that power equals a much lower current on the input end where it draws from the wall outlet.

Mass produced Hub motors out of China have made a huge impact on the electric bike market. There are a large number of E-bikes available on the market today because of the invention of the electric hub motor. Because of hub motors, E-bike manufacturers are able to use just about any bicycle frame to turn it into an electric bike. For better or worse, almost any company can choose to be an e-bike manufacturer thanks to the simplicity of hub motors.

With pedal-assist the electric motor is regulated by pedalling. The pedal-assist augments the efforts of the rider when they are pedalling. These e-bikes – called pedelecs – have a sensor to detect the pedalling speed, the pedalling force, or both. Brake activation is sensed to disable the motor as well.

Since you mentioned the charger, the link you sent me came with a 2 amp charger but it would take 10 hours to charge that size battery. Could I use a larger amp charger like 5 or even more for faster charging? How do you tell what is too much so you don’t damage the battery? Thanks!!

Thanks again for the great info, that is really helpful. I just have one last question. On the XLR connections there is a hot, neutral and ground. It appears on the battery you linked to that there are just two wires, how can I ensure which prongs of the male XLR connection on the Porteur are hot and negative? Also, do I just leave the ground spot on the female XLR connection open since there is just a hot and negative wire?

Some e-bikes have an electric motor that operates on a power-on-demand basis only. In this case, the electric motor is engaged and operated manually using a throttle, which is usually on the handgrip just like the ones on a motorbike or scooter. These sorts of e-bikes often, but not always, have more powerful motors than pedelecs do.

What does that mean?. Well, it is like having another fit bicycle rider helping you pedal, but without their weight. No matter how hard your hills, or heavy your bike is, this motor will always work t…

If your electric bike isn’t giving you the range it used to, it might be time to replace its battery. Batteries Plus Bulbs has a wide variety of scooter and e-bike batteries that will give your ride new life. Just look for your specific model, then pick the battery you want.

I have been thinking of throwing in a 350W front hub motor as well (on a separate throttle) to be used only if and when the rear wheel digs into the really soft sand – to create a 2×2 wheel drive. I’m not worried by different speeds and power of the front and rear motors as they would only be used simultaneously very occasionally and then only if and when the the rear wheel is slipping badly. Regards, Len

Interesting… that’s a beefy looking electric bike! I haven’t heard of Falcon or tested this bike (or anything quiet like it) but the specs are impressive. Note that it’s actually not classified as an ebike due to the large motor, it would need to be 750 watts with a top speed limited to 20 mph, and this could create a liability issue if you crash and damage property or injure someone. Given your desired range, it seems like the super large battery pack would be good, it will impact weight and handling to some extent but that’s the trade, an alternative would be a mid-drive ebike with pedal assist like the Volton 350. Note that the Falcon website doesn’t have an address, just this phone number (855)-661-7337 so it feels less trustworthy than a local dealer or large company that is more willing to expose who they are and potentially offer ongoing support. Hope these thoughts help 🙂

TerraTrikes make great electric recumbent trikes. Here are a few how to tips for converting the Rover and Rambler models, specifically with internally geared hubs. The TerraTrike Rover and the rambler models both are offered with internally geared hubs. It is possible to convert the trike to external gearing, but you will probably want the help of a bike shop that is familiar with recumbents. For a good bike shop,…

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.

Hi Om, most electric bike kits that I’ve reviewed don’t offer regeneration and those that do are incredibly inefficient (like ~20%) so you’re losing much more energy than you capture. It’s a neat feature for helping you slow down when descending big hills and it creates a nice feeling to think that you’re getting a charge but I would not set out to generate electricity by pedaling unless you want to simulate hills and use your bicycle for rigorous exercise. If that is your interest then check out the BionX kits which all offer regen, you can even buy them preinstalled on bikes from OHM and others.

My first question is whether a hybrid or a hard-tail mountain e-bike is best suited for my needs? Most hybrid models I have seen are set up for commuting and since I am a fair weather rider I have no need for added features such as fenders and lights. I do, however, desire the option to mount a rack. I love the versatility and looks of mountain bikes. Bull has a few HT mountain bike models (29ers and 27.5) that may work but wonder if the riding position may be too aggressive and/or the tires too wide (i.e., too inefficient) for riding on the paved road sections.

First off: the info you received about a the battery without a BMS blowing your controller is wrong. It’s always a good idea to use a BMS for safety reasons, but as long as the battery is balanced and fully charged, your controller has no idea if it has a BMS or not. All your controller cares about is if the voltage is correct, which as long as the battery is charged, then it presumably will be.

Finally found it. WOW!! Exactly what was needed. I struggle with conceptualizing verbal descriptions. You solved that! With the new JP Welder from Croatia my first welded build will soon be a reality. Thanks for all you do for eBiking!

Remove all metallic jewelry. This is another tip that I can give from experience. Arcing the contacts on your battery is not something you want to happen ever, and especially not against your bare skin. I’ve had it happen on my wedding ring and once even had a burn mark in the shape of my watch’s clasp on my wrist for a week. Now I take everything off.

Hi Micah, I have been studying your how to build an bike battery, and enjoyed all the tips. I have been having a bit of difficulty figuring out the wiring portion of the construct however. For example, you talk of C, B and P pads and wires you solder to the top and bottom of the pack; the yet don’t put arrows to or refer to their colors for easy identification. The charge and discharge instructions for connecting are gone over rather fast with little for us to identify with exactly where to attach to, etc. Could you revisit your post here and include some baby steps for those who can’t follow the reference instructions you give for wiring the BMS?

the problem i have and the bit im confused on is this, i understand the negative on the entire pack goes to the negative on the BMS and the positive of each parallel cells goes to each sense wire but where are the charge and discharge wires going ? am i corrrect in saying that the positive of the pack goes to the charge and discharge socket on the BMS and that when the pack receives its charge it charges the pack and the discharge is when the pack is under load from the output of the pack i.e what ever its connected to for example your bikes motor? in your tutorial you havent shown how you connected the parallel groups of batteries together in series to give you the final pack voltage and capacitance but i’m assuming you linked them in series to get the toal 36v but on the pictures the first and last cells are split compared to the doubled batteries for electric scooters canada cells you have through out. am i also correct in saying that if you have 2 batteries connected together to form a cell then you dont need a sense wire on each battery because the two batteries are considered to be the same battery and when they charge and discharge they equalize as one shunts the other ? sorry for so many questions i have googled and googled and googled and as Einstein once said the definition of madness is doing the same thing over and over and expecting a different result, many thanks in advance .

  1. I figured this would be a critical step I wouldn’t want to mess up. Thanks for the advice on using the multimeter. That’s good to know as I thought I might need to open up the controller and see which wires went where on that male xlr connection which I guess would be an option too. Thanks again!
