This lets us control each step of the process, ensuring that the spokes are uniform, straight, and undamaged, allowing us to apply spoke-prep to the spokes, oil to the nipple seats, and inspect the rims before…
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. 🙂

You can buy LiFePO4 straight from China from Ping Battery. These batteries are a little bulky, but are safe, and will last over 1000 charges. You can also buy ready made Lithium Iron Phoshate (LiFePO4) or Lithium Polymer (LiPo) packs from BMS battery.
1C charging is too high for most Li-ion. It’s too much to ask for right now, to be able to charge an entire pack in one hour. It can be done, but it’s not healthy for the cells. Aim for 0.5C at the most. I usually don’t go past 0.3C on charging.
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.
That’s exactly correct. You’d start by welding 10 parallel groups of 4 cells each, then you’d connect those 10 parallel groups in series to make one rectangular battery. I’ve done many 10s4p packs just like that for 36V 10ah ebike batteries.
Most commercially available 36V packs are around 10Ah, meaning our pack will be just a bit smaller. We could have also gone with a 4p configuration giving us 11.6 Ah, which would have been a slightly bigger and more expensive pack. The final capacity is totally defined by your own needs. Bigger isn’t always better, especially if you’re fitting a battery into tight spaces.
If you ride a bicycle a lot, chances are you’ll eventually need some replacement parts. We stock Original Equipment Manufacturer (OEM) Parts for all of the electric bikes, folding bikes, and scooters in our store. We also have a number of generic replacement parts like inner tubes, batteries, and drive belts available to get you back on the road.
Fat E-Trike from Sun and E-BikeKit™ at Interbike 2014 Fat bikes and electric bikes were all the rage this year at interbike in Las Vegas. It seemed almost every bike vendor at the show has at least one fat bike model in their booth this year. On top of the fats were the electric bikes. And I think it goes without saying that nobody wants to actually pedal a fat…

From what I can tell, the Faraday Porteur uses a 36V 5.8AH battery made from the same cells I used on the battery in this article. They only have two cells in parallel though, not three like in my battery shown here. You can build a battery just like theirs, or a 36V battery of any capacity. You could make a 12AH battery and triple your total range! Heck, you could even take a premade battery like this one and just replace the discharge cable with a XLR connector – it’d be an auxillary battery over three times as large as theirs for 2/3 the price!
More powerful pedelecs which are not legally classed as bicycles are dubbed S-Pedelecs (short for Schnell-Pedelecs, i.e. Speedy-Pedelecs) in Germany. These have a motor more powerful than 250 watts and less limited, or unlimited, pedal-assist, i.e. the motor does not stop assisting the rider once 25 km/h has been reached. S-Pedelec class e-bikes are therefore usually classified as mopeds or motorcycles rather than as bicycles and therefore may (depending on the jurisdiction) need to be registered and insured, the rider may need some sort of driver’s license (either car or motorcycle) and motorcycle helmets may have to be worn.
Linear packing, on the other hand, will result in a narrower pack that ends up a bit longer than offset packing. Some people say offset packing is more efficient because you can fit more cells in a smaller area by taking advantage of the space between cells. However, offset packing creates wasted space on the ends of parallel group rows where gaps form between the edge of the pack and the ‘shorter’ rows. The larger the battery pack, the less wasted space is taken up compared to the overall pack size, but the difference is negligible for most packs. For my battery, I decided to go with offset packing to make the pack shorter and fit easier into a small triangle bag.
I have a 2015 GNG 48V mid drive, and it starts skipping under heavy load with no pedaling (pulling a bike trailer with a few kids on it). Any idea how I can stop the skipping? I was thinking about looking into a chain guide. One time, I was trying to pedal with the motor, and the chain fell off.
That might of sounded confusing, so let’s talk in real numbers. My pack is about 70 mm high and about 65 mm wide. That means that half of the perimeter of my pack is 70+ 65 = 135 mm. So I need some heat shrink tubing that has a flat width (or half circumference) of between 135 to 270 mm, or to be safer, more like between 150-250mm. And if possible, I want to be on the smaller end of that range so the heat shrink will be tighter and hold more firmly. Luckily, I have some 170mm heat shrink tube which will work great.
I am looking to purchase my first electric bike. I have test ridden many and narrowed my favorites to the eMotion City Wave and the Pedego City Commuter, with 28″ wheels. I don’t anticipate lengthy trips – likely up to 30-40 miles tops, however we live in the hills of NH, so I would be using pedal assist and/or throttle for the tougher climbs. While I love the City Wave ride, I worry a bit about the 350W vs. the possible 500W on the Pedego. batteries for a scooter am 5’8″ and weigh 138 lbs. Your thoughts?
Hi Pete! I did really enjoy the Neo line and it seemed like they sold a lot of them so hopefully there will be packs available for several years. Considering that the same pack was used on all of the different models, I feel like you should be in great shape 🙂

Hub motors come in two different types including geared (usually a planetary design) and direct drive or gearless (relying on larger magnets and no gears). Gears provide leverage, enabling smaller and lighter weight motors to achieve greater output but also produce friction, noise and wear. Most modern geared hub motors are built very well and should last for many years so don’t get too spooked. It may seem counter intuitive but geared hub motors do not add resistance when coasting. This is because they usually contain a freewheel mechanism that can unlatch from the axle and spin with little to no friction.
You commented on the cost without commenting on quality or design or anything other factor. Not really fair. I can buy a house for twice as much as a another house, insane? Likewise you could find a car for twice as much as your current car – is that insane? Without examining the other variables (quality/features/etc) its not even reasonable to begin commenting on the cost.
Another difference is motor rotational speeds. ddhubs are 1:1 and spin slower at 250-300 rpm. The mid drives and geared hubs can spin faster and then go thru reduction gears. There are tradeoffs to both platforms.

Hello Court! I have spent a good deal of time the past few months researching e-bikes. I read your introductory book and nearly every online review you have written over the last year or so. The closest e-bike shops to me are about a two hour drive and are limited in what brands and models they stock (mainly city style bikes). So before I venture out to test drive a few models, I am seeking your advice to narrow down the type of bike and drive train that makes the most sense for my application.
This article first appeared in Electric Bike Report in June of 2013. Since then, we’ve made some changes to our motor selection – our Direct-Drive motors are now all High-Torque 6×9 wound, so they run slower (approximately 15mph at 36v or 20mph at 48v), and our Geared Motors have been replaced by a 500w version, (approximately 20mph at 36v or 28mph at 48v). The Direct-Drive is now our Heavy-Duty motor and the…
very steep hills. The only two drawbacks of a geared motor is a higher possibility of wear due to more moving parts, and a higher noise level than a direct drive motor. But we believe the benefits far outweigh the drawbacks and make the BH Neo bikes a highly compelling option.

BMS’s aren’t required, they just make life easier. As you mentioned, if you don’t use a BMS then you’ve got to diligently monitor your cells and use balance charging to manually balance your cells. A BMS just takes care of this hassle for you. A low quality BMS can cause problems, but good quality BMS’s shouldn’t risk cell damage.
