You can use any connectors you like. I’m a big fan of Anderson PowerPole connectors for the discharge leads. I used this other connector that I had in my parts bin for the discharge wires. I’m not sure what that type of connector is called, but if someone wants to let me know in the comments section then that’d be great!

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.

I then put one set of welds on each cell end of the first parallel group, effectively tacking the three nickel strips in place. Then I added another set of welds on each of the negative terminals of the second parallel group. This gave me 6 weld sets, or one weld set for each cell. Lastly, I followed up those single weld sets with another couple welds per cell to ensure good contact and connection.

The Active Line drive is designed for casual, comfortable cruising and pairs particularly well with bikes equipped with an internally geared rear hub. Featuring the full suite of sensors – including cadence, speed, and torque, the Active Line offers great hill climbing torque for moderate to steep hills. The Active Line drive offers a maximum assist speed of 20 mph.

Hi Lisa! Front hub motors can be fine, they do tend to impact steering a bit and can spin out easier but are way simpler to either install or service because they aren’t surrounded by gearing cables. The fork on most bicycles isn’t as strong as the rear dropouts (especially if there’s a suspension fork) and this is another reason why most purpose built models don’t use them. Some simple city bikes do however and you can get a good example of this with EZ Pedaler. They opted for front motors because they put geared hubs in the https://en.wikipedia.org/wiki/Electric_bikes which makes shifting at standstill possible, reduces exposure to bumps if the bike tips and is generally cleaner and less likely to need tuneups (but only offers 3 gears in this case). I hope this helps you to find the perfect ebike, feel free to post in the forums if you’d like more info or some help from fellow electric bike owners 🙂

Your battery pack size is based on voltage and amp-hours. The higher the voltage and the higher the amp hours of your battery, the more range your battery will give you. A 48V 10-Ah pack gives you 480 watt hour (48 X 10). This gives you an easy way to determine exactly how much battery you are buying. The wattage of a battery is the only accurate determinant to judge what range your finished ebike will have.

It’s what’s inside your motor that sets it apart from the rest. Quality parts and assembly We’ve written here before about how to choose a motor, the different types of motors, the performance differences between motors, etc. But today I want to show you what makes our motors different from other hub motors.

Wow, that’s a really interesting way to do it. So their auxiliary battery connects to the charge port of the primary battery, which means it’s not actually powering the bike but rather just charging the primary battery, which then powers the bike. Not the most efficient way to do it, but it’s simple and elegant.

If you are concerned about the speed and power of an electric bike, pay attention to the motor size. Electric motor size is measured in watts and usually ranges between 250 and 750. When deciding on the appropriate amount of wattage, think about factors like the weight of the rider and the desired speed and terrain for the bike. If your child will mostly be on a flat surface, lower wattage should suffice; if they are planning to ride up and down hills, look for a bike with a larger motor.

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.

I just have a simple question: I would like to replace the Nicad battery 24V / 5Ah of my old Yamaha PAS XPC26 with a 7s3p and maybe try a 8s3p for something more “punchy” (hoping the controller will not burn …) . Do you think I can buy a 10s BMS and use it with a 7s or 8s battery? In this case, what should I do with the spare balance wires ?

if you carry the right tools its actually not that hard. doing it on the side of the road usually takes me about 20 minutes. it can vary from set up to set up, as you have to take apart the assembly off the bike and then pull out the tube, which can be difficult on some tires that have tough rubber treads. i would also suggest that someone care a head mount flashlight (my local dollar store sells them) as it will allow you to change them when its dark out.

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 😀

Sunstar is based in Japan, and here is a PDF of their most recent mid drive motor system. Sunstar has a 2001 patent on this drive, and they are suing Bafang in Germany over the BBS01/BBS02 system that has recently become popular. That patent is 13 years old, so perhaps Bafang felt they were on safe legal ground in by copying it?

I’m planning on building a 10S12P pack for usage on a custom DPV (Diver Propulsion Vehicle). For packaging purposes, it would be best for me to split the battery pack in several battery modules instead of a single block of cells.

Original Equipment Manufacturer Parts (OEM) have been designed by the manufacturer to be compatible with your scooter, folding bike or electric bike. That holds true for parts made by Brompton, Tern. Bulls, Stromer, Dahon  and many other brands. Find original replacement parts for the BionX electric bicycle conversion kit, like batteries, chargers, consoles, motors and wiring. NYCeWheels sells parts for Brompton Folding Bicycles whether you need to replace a part or just want to stock up with a spare, just in case. NYCeWheels even sells some hard to find replacement parts and accessories, like those for the eBike that is no longer in production.

Hi Micah, thank you for your advice. I am not going to touch that battery. I know this may be a lot to ask, but would you build me a battery for my velomini 1 ? It doesn’t have to be the one that fits in the frame, I could put it in a bag and hang it on the handlebars or something. If more convenient you can email me directly at dlimjr at yahoo. My sincere thanks and may you and your family have a happy holiday.. Don, San Francisco

Thanks so much for this excellent information. I was wondering how to calculate the total amps for the entire battery? I’m trying to determine watts from this as I have a 24V 500 watt Rayos electric bike and am working to build a 24V 20 Ah battery (7s7p) battery and would like to know what watts it is batteries electrical of providing.

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?

You don’t know Ecospeed. If you did, and if you tested, you would realize that Ecospeed should be rated as the number one mid drive system out there. Based on years in business, satisfied customers, technology, engineering, and service. I know, since I have had Ecospeed for 5 years or more and I have two of the latest iterations of Ecospeed (one mtn bike and one recumbent) and use it to climb 2500 vertical feet of logging roads regularly. And it is fantastic.

I’ve gotten so many different BMS’s from so many different suppliers so I’m not 100% positive, but I believe it was from this source: http://www.aliexpress.com/item/NEW-Battery-Protection-BMS-PCB-Board-for-10-Packs-36V-Li-ion-Cell-max-30A-w/32291193643.html

Not all e-bikes take the form of conventional push-bikes with an incorporated motor, such as the Cytronex bicycles which use a small battery disguised as a water bottle.[45][46] Some are designed to take the appearance of low capacity motorcycles, but smaller in size and consisting of an electric motor rather than a petrol engine. For example, the Sakura e-bike incorporates a 200 W motor found on standard e-bikes, but also includes plastic cladding, front and rear lights, and a speedometer. It is styled as a modern moped, and is often mistaken for one.[citation needed]

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.

craig it should not damage your controller. When you connect two batteries together in parallel it will actually extend the life of both batteries because you are not taking as much of https://en.wikipedia.org/wiki/Electric_bicycle toll on them when discharging and hopefully not running them down as low.

Imagine a full suspension electric mountain bike with a mid drive motor. The front and rear wheels can rebound quickly and efficiently because their mass is lower and the overall weight of the bike itself is connected to the main section of the frame making it feel fluid. When approaching a large hill, the rider can shift into a low gear providing mechanical advantage making it “easier” to pedal and climb. Just as the rider benefits in this scenario so too does the motor. While the overall speed of the bike is reduced for climbing, neither the rider, nor motor will be over exerted thanks to the gears. In this scenario the rear dropouts also endure less strain because the weight and force of the motor are spread out and connected to the major tubing of the bottom bracket.

When it comes to the nickel strip you’ll be using to connect the 18650 batteries together, you will have two options: nickel-plated steel strips and pure nickel strips. Go for the pure nickel. It costs a little bit more than nickel plated steel but it has much lower resistance. That will translate into less wasted heat, more range from your battery, and a longer useful battery lifetime due to less heat damage to the cells.

Wattage isn’t the unit of concern here – torque measured at the chain’s drive sprocket is what counts. Motor wattage ratings are a gross measurement of power, or horsepower. The efficiency of the reduction stages, as well as the motor itself are not generally included in the manufacturer’s wattage rating. Beyond that, there’s the overall gear ratio which serves as a torque multiplier. The point is: Even an efficient low wattage motor using a very high ratio reduction system can produce sufficient torque to stress a chain and everything else at the rear wheel. Example: Picture a 250W motor driving a 100:1 reduction on a 500 lb. trike climbing a San Francisco Hill with Michael Moore as the rider.

You want to use unprotected cells because your BMS will be handling all the protection, and you don’t want individual cell protection circuits getting in the way or limiting current draw unnecessarily. So use only unprotected cells when building big multi-cell packs like these.

This bike only needs to get me to and from work on paved roads (and some sidewalks) and I don’t plan to ever take it on any trails but it does need to be able to handle hills. I have a local bike shop near me, but they currently don’t sell anything electric (the guy did warn me against Pedego bikes, though…saying they were not good quality. I mention that to say this: I don’t know how good any local service options are going to be for me, so simplicity and having a bike that works are important. Also, I’m on disability and don’t have much money, so price is a factor (that’s why the Flux on Indiegogo appeals to me).

So let say main point to count the power is to count the power is to know what type of the controller i have (i have check my batt connection goes to PCB which has sensors it self and whole unicycle controller… ) how to know ? Or in primitive way i can count like my batt is 20A and 36W so max power can be 720W but its peak on continues?

Thank you for the article! I am currently making a battery for an electronic skateboard, so I need the layout to be as thin as possible to allow ample room underneath the deck. Currently, I have 6 packs of 3 cells welded in parallel, and would eventually like to create a battery which is 9 cells long, 1 wide, and 2 high, for 18 in total (the two packs of nine would then be welded in series). I am wondering if I could be able to make 2 battery packs by welding 3 of my current 3 cell packs together in parallel to make a long, yet skinny pack, and then welding both packs of nine in series using the alternating system. Essentially, I would be creating a pack that would look like 3 of the ones you show above when making your first series connection. Let me know what you think, and thank you!

I’ve checked with a few people that have bought 220V european welders and used them in the US, and they all say they work fine (besides one that broke a few months later from an unrelated issue). As far as I can tell, regardless of whether its half or full phase, the transformer inside still sees the approximately 220V it’s looking for. Have you tested yours on 220V yet?

So I’m going to first use a wider (285 mm to be exact) but shorter piece of shrink wrap to go around the long direction of the pack. That will seal the ends first, and then I can go back with my long and skinny piece of heat shrink to do the length of the pack.

A better and simpler solution would be, as you said, to carry a second battery and just swap the connector from the old battery to the new one when the old battery is depleted. There are a few types of bottle batteries out there, I recommend googling “bottle battery” if you haven’t yet, you’ll likely find a few options. I don’t know if this is the same model as yours, but some common styles similar to your description can be found here and here.

It’s hard to say for sure without seeing your work. I imagine that either you have a bad connection somewhere, or else you have some cells that are weakened and drop their voltage too low when a load is applied. I didn’t quite understand from your message: did you rebuild the battery using the cells in your Frog battery, or did you start with new ones? Old or damaged cells could cause the problem you are experiencing.

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.

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 http://electricbikebatterycharger.com 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.

I’m planning on building a 10S12P pack for usage on a custom DPV (Diver Propulsion Vehicle). For packaging purposes, it would be best for me to split the battery pack in several battery modules instead of a single block of cells.

You’ll also notice in the following pictures that my charge and discharge wires are taped off at the ends with electrical tape. This is to keep them from accidentally coming in contact with each other and short circuiting the pack. A friend of mine recently tipped me off to another (and probably better) option to prevent shorts: add your connectors to the wires first, then solder them onto the pack and BMS. Doh!

I am planning to build a 14s7p pack with the GA batteries for a little over 1 KW of power. I went to the BesTechPower site and their are several 14s BMS’s there. Which one would you recommend for a battery this size? Can you send/post a link to the specific on on their site? thank you.

Hi Zoom, I really like the Haibike and Felt models because they offer full suspension or hardtail trail ebikes. They are well balanced, efficient and fairly quiet. You could build an ebike using something like the e-RAD kits if you want throttle mode and are willing to get your hands a little dirty 🙂
