Many people are tempted to use cheaper 18650’s sold under names like Ultrafire, Surefire and Trustfire. Don’t be one of those people. These cells are often marketed as up to 5,000 mAh but struggle to get more than 2,000 mAh. In actuality, these cells are just factory rejects, purchased by companies like Ultrafire and repackaged in their own branded shrink wrap. These B-quality cells are then resold for use in low power devices like flashlights where their weaker performance is less of an issue. If a cell costs less than $2, it simply isn’t worth it. Stick to the name brand cells, like my favorite Samsung cells, if you want to build a safe, quality ebike battery.

The Bosch mid-drive motor system has quickly become the leading motor system in Europe since its debut at Eurobike in 2010. Bosch’s quick success can be chalked up to many things, but perhaps most important has been its renowned reliability and performance. By building on the middle motor pioneered by Panasonic in the mid-90’s, Bosch started with an efficient and reliable design. But Bosch improved upon what Panasonic had been doing in important ways: adding more sensors (torque, cadence, and speed), a single chainring design like Impulse, for better reliability, and designing an advanced console for better control.

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.

Make sure to consult the wiring diagram for your BMS, because some BMS’s have one more sense wire than cells (for example, 11 sense wires for a 10S pack). On these packs, the first wire will go on the negative terminal of the first parallel group, with all the rest of the wires going on the positive terminal of each successive parallel group. My BMS only has 10 sense wires batteries for motor scooters so each will go on the positive terminal of the parallel groups.

Hi Clyde, each electric bike or brand uses a different system with different displays, throttles (thumb or twist) and pedal assist (cadence or torque). I’ll try to break it down for you quickly but you can see me using and explaining each system by watching video reviews here on the site 🙂

Court- Excellent article (and I have read a lot). I wonder if you can weigh in on a system I am trying to build. I have a Montague Paratrooper (a bike that folds). I need to fold it and put it in a drift boat. It needs to weigh as little as possible and must have a removable battery and about a 10 mile range with an average speed 20+ mph. I had sort of “settled” on a Bafaang 750 or 1000 watt with Dolphin 52V battery (kit at Lunacycle). Now I am not so sure after reading the pro/con of your article. Cost is certainly an issue and ease of installation. I have been biking with out the motor, and I have numerous fairly steep (6-8%) hills. What do you think I should do? Rear hub, smaller battery. Thanks !

This is the old technology for e-bikes that is heavy as bricks and does not have longevity. Lead acid will double the weight of your electric bike. Unless you have to because of money restraints, we advise to steer way clear of lead acid batteries.  Your bike will have a completely different feel and range if you spend the money on one of the new lithium technologies.

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 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.

I was wondering, though, if I could use thick gauge wire instead of nickel strips (copper wires are much more accessible). Would there be any downsides to that, given that I’m going to be using solder anyway?

Cyclone-USA introduces a completely new electric bicycle motor kit with more power and more range than any other bicycle motor kit on the market today. The unique brushless DC motor features an integrated planetary gearbox that significantly multiplies the motor torque. The result is fantastic climbing and cruising power from a small, efficient motor. Using the standard battery pack, the Cyclone motor system can achieve 30 miles without pedaling and 40-50 miles with very moderate pedaling.

This is a great article, I was thinking about making including the batteries and controller in the front Wheel/Motor hub ala (Copenhagen Wheel & FlyKly) and then create something like a solid acrylic or fiber wanted to cover the whole thing and rearrange the batteries.

Persistence Market Research in September 2017 predicted a global market growth of 4.7% CAGR during the period 2017-2022.[37] Asia-Pacific excluding Japan (APeJ) is a lucrative region and is expected to show high market share by the end of 2022.

You’ll also want to test out the battery with a fairly light load in the beginning. Try to go for an easy ride on the first few charges, or even better, use a discharger if you have one. I built a custom discharger out of halogen light bulbs. It allows me to fully discharge my batteries at different power levels and measure the output. This specific battery gave 8.54 Ah on its first discharge cycle at a discharge rate of 0.5c, or about 4.4 A. That result is actually pretty good, and equates to an individual average cell capacity of about 2.85 Ah, or 98% of the rated capacity.

Karl at electric-fatbike.com is the Bafang mid drive guru, and even though the BBSHD only maxes out at a slightly higher amperage (30A vs the 25A on the smaller BBS02), the extra copper mass in the BBSHD stator means that at 52V X 30A = 1560W of power, the BBSHD barely gets warm, because it is larger and also sheds heat better. Even if used at the same watts as the BBS02, the stator of the BBSHD is 66% wider, so it will definitely make more torque.

Ultimately, I have a love hate relationship with mid drive systems because I appreciate their efficiency but miss some of the zip and instant gratification that hub motors offer. They are often noisier as well… Some mid drive systems can feel clunky and frustrating to shift but others are actually very satisfying to use. I’m talking about the Bosch System and similar high quality offerings which can actually sense that you’re trying to shift and gently cut the motor so you won’t strain the drivetrain. The final advantage with mid-drives is that the motor weight is located centrally on the frame in addition to being low. This is going to provide stability when riding or lifting the ebike for transport or storage. One quick downside is that the motor may be vulnerable to rocks and logs on the trail with a mid-drive because it’s not surrounded by spokes and a wheel like hub motors are. In my experience, most mid-drives are protected with some plastic or metal casing that can take a few hard hits before suffering damage.

Hi Craig, the ST2 is an awesome ride with some really neat features. I wouldn’t feel comfortable recommending it over another model until I knew your height, weight, desired distance and terrain (off-road, packed trails or mostly street). I personally have some neck and back issues so I like the full suspension ebikes with large knobby tires for a bit of trail riding. I’m not a large rider so I prefer my frame size to not be too large or heavy and I don’t want to go over 20 mph so that helps me focus on a specific group of bikes… If you share your details maybe I can make some more informed recommendations here.

  1. 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.
    The Flux ebike is neat and priced relatively low, it’s not a super large bike and won’t offer the same power as a 48 volt Pedego but it’s going to be lighter weight. Depending on your body size and weight it could work well enough and has the added benefit of mid-drive which frees up the front and rear wheels for easy maintenance. The downside is more shifting and higher forces on the chain, sprockets and derailleur. Have you checked out the Rad Power Bikes at all or maybe the VoltBike models? These companies ship internationally, have a large selection of styles and are priced pretty well. I hope this helps guide you, poke around the site here a bit and use the advanced search engine to narrow down by price, size, power etc. 🙂
    Unfortunately, he has no upgrades for me. I have since purchased a Cyclone crankset (because the GNG unit failed in 3 days). If the chain falls off, I will get a Wolf Tooth Components Drop Stop chainring.
    In some cases a front mounted hub motor is preferred because it allows an internally geared hub or continuously variable transmission CVT hub such as the NuVinci to be used in the rear. Some of the newest electric bikes like the Smart ebike combine an internally geared hub (that the cyclist pedals) with a hub motor and are able to put both in the rear wheel.
