“mountain bike with electric motor +electric bike batteries lithium”

Hi Jasmine! Interesting question, I think you could use a geared hub motor mounted in a 20″ wheel but am not sure if that would match your wheelchair perfectly or mount to a side axle vs. one that’s built into the hub (most ebike hub motors I’ve seen are permanently fixed to the axle). Lots of companies offer basic motor, battery, controller kits but this one from Dillenger appears to come in the small 20″ wheel size. Maybe there’s a way to add a mounting system between the two rear wheels to have this third wheel act as power? The other challenge is reverse, most electric bikes don’t offer this but one company called E-BikeKit does with their trike conversion kit here which may also come in 20″ wheel size. I hope this helps you get started, if you call the E-BikeKit company ask for Jason and maybe he can even give you some more advice as they offer some models designed to be more like personal mobility trikes vs. fast commuter bikes. One such model is their Liberty Trike here.

Your method of using the tubes might work but I still worry about how much current you could safely pull out of those connections. You can definitely charge the way you described but trust me, charging 2 or 4 cells at a time gets VERY frustrating. You’ll be spending days, maybe a week, getting your battery all the way charged again.

This Saturday, Oct. 7, Tim Sway will showcase his “UpTriCycle” at the Greater Hartford Mini Maker Faire. Sway calls the UpTricycle an “off grid, electric, solar charging mobile maker space and carrier for upcycling makers.” He uses minimal tools and footprints in his creation for unlimited potential. On his YouTube page, Sway made a comparison video between a gas-powered trike and an electric trike. He purchased a gas-powered trike first,…

Lithium batteries are not 100% fire-safe. Some batteries are more dangerous than others, depending on the chemistry, whether it has BMS or not, and what kind of casing the battery is in. If the battery is cased in metal its less likely to burn your garage down, than if its encased in plastic. Also be aware that all BMS’s are not alike, some are good and others are crap, just like anything else in life.

Manufacturers usually rate their cells’ capacity at very low discharge rates, sometimes just 0.1c, where the cells perform at their maximum. So don’t be surprised if you’re only getting 95% or so of the advertised capacity of your cells during real world discharges. That’s to be expected. Also, your capacity is likely to go up a bit after the first few charge and discharge cycles as the cells get broken in and balance to one another.

Pedelecs are much like conventional bicycles in use and function — the electric motor only provides assistance, most notably when the rider would otherwise struggle against a headwind or be going uphill. Pedelecs are therefore especially useful for people living in hilly areas where riding a bike would prove too strenuous for many to consider taking up cycling as a daily means of transport. They are also useful when it would be helpful for the riders who more generally need some assistance, e.g. for elderly people.

What a great article! It has opened my eyes to lots of possibilities. Being new to this I had a couple of questions. I am interested in building a spare battery to give me more range on the Faraday Porteur. My question is how to connect the battery I would build to the bike. The main battery resides in the downtube and the connection is hidden. They offer an ancillary battery that plugs into the charging port which is what I would like to build myself rather than buy. Do you think this would be possible? Where could I find a connector that would match? Any concerns? If so, what other options do you suggest? Thanks so much for the help!!

Hi Lalith, cool name you have! If you are buying a high volume of electric bike motors and batteries, then you could probably buy direct from China and maybe use a website like Alibaba. However, if you need a small or medium number, maybe you could research a company like Clean Republic. I reviewed their affordable Hill Topper kit a while back and thought it was good. If you are buying for Africa, it might be easiest to source parts in Africa or find a wholesaler in China that can ship there vs. going from China to the US and then Africa. I hope this helps you! Be careful if you are planning to buy and then fly with products like this because high capacity Lithium-ion batteries are not usually allowed.

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.[14]

If you want to go 50mph and have a 500 or 1,000-watt monster motor on your electric bike you’ll need big expensive, heavy batteries, and you might as well buy a motor scooter or motorcycle. If you wan…

According to some quick research I did, a city block is about 100,000 square feet which means that you can fit 17 blocks per mile. Given your round trip distance of 14 blocks… that’s way less than one mile and in my experience the new EVO line of Easy Motion bikes (which have ~417 watt hour batteries) will get upwards of 15 miles per charge even after hundreds of uses and on uneven terrain. Of course, your weight and the hills and wind all have a factor but you should be very good for just a mile or two of use.

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.

The last step of wiring the BMS is to add the charge and discharge wires. The pack’s positive charge wire and discharge wire will both be soldered directly to the positive terminal of the 10th parallel group. The negative charge wire will be soldered to the C- pad on the BMS and the negative discharge wire will be soldered to the P- pad on the BMS. I also need to add one wire from the negative terminal of the first parallel group to the B- pad on the BMS.

After writing my question, I did more research on these cells regarding overcharging and over-discharging and I see where you’re coming from regarding not having connections between the parallel cell blocks to smooth out differences between individual cells. So as a permanent installation, it’s not going to work. However, I’ve had another thought, which I’ve put at the final paragraph.

I’m not sure what cells exactly you’ve got there, but a good replacement cell (assuming it has similar specs to your cells, which you’ll have to confirm) could be the Samsung 26F cell. It’s a good quality economical battery cell. I’ve gotten them from here and had great experiences with the vendor: Samsung 26F 18650 lithium battery cells

We’ve learned some users love connectivity to our Electron app, while others will prefer to ride without it. That’s why we’ve engineered an app that lets you choose whether or not to use its features like distance and speed tracking, battery life readouts, assist levels, and ride mapping. If those aren’t for you, just calibrate your wheel once with our app, and then enjoy the wheel free from any device.

I wouldn’t say incompatible but us 220 uses the full phase peak to peak of both legs of the elec drop. European and others uses a half phase (I believe) where zero to peak is 220v. Have you had a chance to look into this for me as my welder and box of new 18650’s are sitting idle waiting for me to start welding. Thanks

What could I build to go up a mountain path? say 4000 ft long. It’s too steep for me & most bikers to pedal. I want to assist ..but the motor drive train will do most of the work. Down hill one needs good brakes or something electric generating. I bike 5 miles now up and down local hills but walk up the steep hills for sure. For a good bike http://bestelectrichuntingbike.com …I would enjoy building a few prototypes. Any advice appreciated…I love to bike on green trails!
