This is how most Asian batteries are built, since they use the same size aluminum or plastic case, but offer different sizes and capacities of batteries in the same case. I’ve used arts and craft foam, which often comes in sheets up to about 5mm thick (and I use a few layers to fill larger gaps). For MUCH larger gaps where that thin foam is less desirable, I’ve seen people use styrofoam or even that green molding foam often used in pots to hold up fake plants. That stuff is a fairly rigid though, so maybe a combination of that stuff and a layer of softer foam for cushioning would be good.

There are many different ways to accessorize an electric bike or folding bike. Some people prefer safety above all. For them, some popular accessories are helmets, lights, and bells. Other people prefer commuter accessories. No matter what you’re looking for, you can find it in one of the sections below.

Court, great site you have here. I will tell you want i think i want but realize i don’t really know what i am talking about: i am looking for the best bike i can get. i want speed, endurance, great on hills, smooth ride and easy gear change, light weight (but not if it is in exchange for a lesser battery), max battery (48v and 17/18ah, and max watts) and anything else you can think of. i am a little confused on the different systems, but want the best of all worlds (of course) but realize that there will be compramise. maybe you can tell me the best balance of all that i am looking for as i am not price sensitive. What do you think of the Stromer ST2? any other bikes i should look at? c

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.

For BMS’s, the highest quality ones come from a company called BesTechPower but they are more expensive. I have mostly used BMS’s from AliExpress. I’ve linked to a few examples of BMS’s I’ve used in the article above.

hi i was considering adding a second set of batteries to my ebike in parallel to double the range but heared on a thread somewhere that this can damage/overload the controller which i suspect is a load of tosh but can anyone confirm/clarify this as i assumed the amp hour capacity was just that and the max amp output was just that, the maximum that can be drained at once, my understanding is it doesnt matter what amp hr the pack is as the amps drawn into the controller is governed by the demands of the motor which wont change if i have 2 packs connected.

Hi Court, Love your work. It appears that you have one of the best jobs going! Just wondering if you are considering reviewing the 2016 KALKHOFF INTEGRALE 8 any time soon? If so I would be interested to hear the noise level of the Impulse EVO RS mid drive system coupled with the Gates belt as I intend to commute 75 km per day and want a really quite and fast commuter

Hi Kim! Great question… I’ve heard some ebike companies and shops guestimate that 180 lbs is a good cutoff when jumping from 350 to 500 or 750 watts (750 is the highest allowable in the US). I’m sure you could get away with a 350 just fine, especially if you pedal along a little to help it get started each time and ride mostly on flats. Here’s a video interview I did with an individual of similar weight who was riding a 350 watt motor for over two years and using a throttle with higher powered 48 volt batteries… you can hear some grinding when the bike starts and I believe this is based on accelerated wear and tear. I hope this helps and welcome you to share what you choose and how it works down the line. I personally appreciate the compact size and efficiency (and lower price) of 350 watt motors but most people would recommend that you aim for 500+ watt in this case.

I’m buy a emotion bike 350 watt I’m going to ride it back and fourth to work going to work Is 7 blocks and 7 blocks back will it be fast enough or have the power I’m spending 3 grand I just want to know if I’m doing the right thing we don’t have many places to buy bike like this in Alaska so there hard to find

This kit comes stock with two chainrings, a 32T and a 48T. This kit has been run at 48V and 72V, the motor runs cool at 30A, and gets warm at 40A. Using 72V X 40A =2,800W, and this is the most power that should be run through the bikes gears. More power than this and you should run a chain directly from the motor to the rear wheel, or…use a large hub motor.

I placed the first parallel group positive side up, and the second parallel group negative side up. I laid the nickel strips on top of each of the three sets of cells, bridging the positive caps of the first parallel group with the negative terminal of the second parallel group, as shown in the picture.

There are many different types of 18650 cells out there to choose from. I prefer to use name brand cells from companies like Panasonic, Samsung, Sony and LG. These cells have well documented performance characteristics and come from reputable factories with excellent quality control standards. Name brand 18650’s cost a bit more, but trust me, they are worth it. A great entry-level cell is the Samsung ICR18650-26F cell. These 2,600 mAh cells should cost somewhere around $3-$4 in any decent quantity and can handle up to 2C continuous discharge (5.2 A continuous per cell). I get my Samsung 26F cells from Aliexpress, usually from this seller but sometimes I’ve seen a better price here.

Introduced in the summer of 2014 by the company Sachsen, the large diameter of this kit is to make up for the lack of internal gears that other similar kits use. It provides 250W, and due to being direct drive, it should likely be very quiet. Thanks to ES member Miles (from the UK) for the link.

These have become the default battery, capturing over 90% of the market. But to complicate matters, there are many different kinds of Li-ion batteries. On the plus side, Li-ion batteries last longer and generate more power for their weight than other batteries. On the negative side, they are fussy little creatures, and require a genius-inspired smorgasbord of electronic features to prevent them from self-destruction and even catching fire! Of course, none of those are your problems, as the manufacturer will have sorted out the genius side. But like all good things in life, this comes at a price: this battery type is very expensive, and shows little sign of getting cheaper.

– BMS/Greenbikekit are now selling cased or shrinkwrap LiFePo batteries based on high capacity cylindrical cells probably from Headway and with a BMS. These have a higher C Rating between 5C and 10C. This makes a 48v-10AHr battery useable in a high performance kit with 30-40A max. Using this with a 1000W-1500W motor/controller should work fine. This is heavier than LiPo but close to the holy grail. Long lasting, safe/easy/convenient, high power.

I feel this motor is a better pick for off-road compared to the BBS02 (even if you are happy with only 750W). This is because the GNG has more copper mass, and it sheds heat well, so it can take more power for longer. We will be getting our hands on a third-party upgrade kit that fixes all of the weaknesses of the GNG next month (look for our review soon).

The Electron Wheel fits most bikes with rim brakes, and doesn’t need any wires or throttles to operate. Just use your bike like you always have, but enjoy the ease of a pedal assist experience. You’ll be hooked after experiencing how the wheel neutralizes most hills and allows you to commute without breaking a sweat.

You want to be really sure you get this part right, and if you aren’t certain, I’d recommend having an electrician or the company help you. But you can determine positive and negative on the charge port by using a digital multimeter on the DC voltage setting. Probe between the three pins on your bike’s charging port to find which pins give you a positive readout of between 30-42V (Depending on level of charge). When you find it, the positive pin will be on the red probe and the negative pin on the black probe. Be careful not to short the pins together or touch the probes together, those XLR connectors are cramped quarters. And again, make sure you’re certain you’ve got it right – connecting something backwards could damage your bike’s battery.

THIS BIKE WOULD NOT COME CLOSE TO WHAT YOU WANT. YOU WOULD NEED A ROLLING BATTERY ON WHEELS. I have a Walmart bike with a 48 volt 1000 watt brush less motor. I use six 5000 watt 6 cell lipo batteries from Hobby King. I only charge to 4.05, and I only discharge to 3.7. even under a load. I have a little volt meter to watch the voltage so I never go below 3.7 volt, even under a load. I have two Reedy 1216-C2 chargers that can be set to max cell charge of 4.05 max per cell. Li-poly if treated right are safe enough for me. I always charge on a metal surface or inside a large pot or pan. If the battery were to catch fire there is nothing around to burn. Just nasty fumes and smoke. From my experience lipo batteries can put out a much higher current than lion, which can get me up the hill faster for less money. Six 5000 watt 6 cell lipo batteries can put out about 750 watt hours. Mine don’t because I don’t charge to 4.2 and drain down to 3.2 per cell. To get the watt hour rating (Ah × V = Wh).

Hmm… All of these are going to be impacted by rust if he’s near the salt water a lot. I’d probably go with the mid-drive BBS02 just for torque and balance given the difficult soft terrain. To answer your question about torque on geared vs. direct drive, I find that geared is more powerful and lighter weight but also louder and sometimes less reliable long term. If you want to go the cheap route I’d go with the geared rear hub (no front hub motor… just more to break). You could consider a front hub only to make it two wheel drive by him pedaling to move the rear wheel and the front wheel using electric but then it might spin out more. The front wheel would probably be best protected from the sand and water and the easiest to install… but again, less traction there as most body weight goes towards the rear wheel, especially when accelerating. I’d love to see pictures of the end result and hear your thoughts in the forum, maybe others could chime in on this subject there as well.

I assume you mean 52V (14s, or 14 cells in series) which is a somewhat common lithium ion battery configuration. It works with most 48V setups but provides a little more power than a standard 48V (13s or 13 cell) battery. A good charger I recommend for 52V 14s batteries is this one.

Although the motor is the same, every part of this drive is very strong and uses the highest quality components, including a 25mm wide primary reduction belt, instead of the GNG’s 15mm wide, and…a #219 kart chain for the secondary, which is rated for over 20-HP (15,000W). By moving the motor-freewheel from the right side, over to the large primary driven pulley on the left, the reduction has been improved to 33:1 (compared to the original GNG reduction of only 21:1).

If you don’t have an actual heat gun, you can use a strong hair dryer. Not all hair dryers will work, but my wife’s 2000 watt model is great. I own a real heat gun but actually prefer to use her hair dryer because it has finer controls and a wider output.  Just don’t go mess up your wife’s hair dryer!

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.

Ultimately, hub motors allow the rider can choose whichever gear they want, pedal at any cadence desired and apply varying force with each stride without playing a material role in how the motor functions. I love hub designs for this reason, there’s nothing pulling on your chain, making it difficult or jarring to change gears… but while the motor is always ready to go, it’s not always performing optimally (for either power or speed).

Thanks for the article, Court. I’m researching so much it feels like a part time job! I have a morning newspaper route that is about 22-25 miles and I would like to start using an ebike for the delivery, as weather permits. According to your article, I’m not going to be able to escape a compromise on some level. If I understand correctly, the constant starting, stopping, and slow speed adjustments could be taxing and uncomfortable with a geared hub. I’ll post my unique situation in the forum instead of hijacking this space.

Loved your comparisons as I’ve been thinking about an e-bike. I ride rurally with gravel roads and lots of long hills, some up to 3 miles and some steep. The plan was to take my cross bike and install a kit but not sure what brands are out and what type would work for my setup especially after watching your hill video. The other issue is durability and dealing with gravel dust. I’d hate to wreck and break something and would gravel dust ruin internal parts? Thanks!

it would be applying huge amounts of force to the chain, which because of rust could become a weak point – if the chain were to snap, then https://en.wikipedia.org/wiki/Electric_bicycle rider would be without any power whatsoever and might end up pushing his bike for 5 or10 km through soft sand while trying to get home after a long day’s fishing – I suppose he could always carry a spare chain.
