“29 hardtail mountain bike -electric motor for bike”

Update: it looks like my nickel strips might be pure nickel after all. The salt water appears to have a suspension of brown precipitate which looks and smells like rust. However, after fishing the nickel strip out and rinsing it with water, it still appears to be silver in colour and not rusted:

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!!

Yes, I’ve seen this problem. Homes that have only a 10A circuit breaker are often not enough for these welders. The room I wanted to use mine in had a 10A, so I switched it for a 20A breaker at the breaker box and now it works fine.

good company, good product, simple upgrade, EXCEPT, it involves brakes & axle bracket widths too, which makes ordering right tricky. Wide means u can have disks, narrow & its rim only (the motor is widish).

For a complete write up on LiFePO4 care and trouble shooting read our story here. LiFePO4 cells nominal voltage is generally from 3.0-to 3.2 volts, and generally, lifepo4 is a heavier and less power dense than available LiPo batteries and is not capable of as high of amperage discharge.

This kit has also been run at 72V X 30A = 2,200W/3-HP (with a different controller), but be aware that this level of power requires a swap to a chain primary reduction, or a wider belt. Also, the GNG allows for a stronger crankset to be swapped-in for riders who like radical jumps without bending the spindle (the BBS02 crankset cannot be upgraded).

2) Try measuring the voltage of the battery while you plug it in and attempt to power the bike. If you see the voltage drop instantly when you turn on the bike, you’ll know you’ve likely got an issue with weak cells or a poor connection that causes a voltage sag issue.

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.

The second big change is that the motor now runs at 48V, making the motor both accelerate and regenerate much more efficiently and powerfully. Finally, the fit and finish of the Syno-Drive has been considered from the perspective of service. Instead of a bolt-on axle, the Syno-Drive uses a modern thru-axle for added rigidity and easy removal.

If you want a LiPo battery pack, one of your better choices if you want to save money and have a lot of output amps is build one of your own from a Hobby King packs. This requires a lot of time and knowledge, not only in building the pack but also in managing it.  LiPo batteries can be extremely dangerous and prone to burst into fire if not assembled with a lot of precautions (BMS) and cared for properly.

Hi Micah,I am from INDIA want to construct a 36v,15 ah,peak current 15 amp,continuous current 6 to 8 amps. Now ipurchased 20 pcs new IFR 18650 lifepo4 rechargeable cells,and a BMS36v,lifepo4 BMS12s forE.Bike lithium battery pack 12s,36,v,PCm.How many cells total i have to use for my aim?What kind of charger (specification) i have to purchase? Your article and reply to questions are interesting.please guide me.

I reached out to the company, because I’m very interested in this system. They currently only operate in Austria, Germany, and Switzerland, and the commented that they are only interested in slow growth. There is a Canadian reseller though, but I can’t find a site.

I hope someone can recommend another spotwelder or some other kind of Technic to fuse batteries with wire (except soldering) . This has been an expensive ordeal and if not even a techlab with endless lasers cutters and cool cants get this machine even to power up, its something wrong with the machine.

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.

at an extremely high efficiency (up to around 80%), doing more with less wattage, and thus not heating up too quickly while giving plenty of torque. In fact, in our testing of the new drive we’ve found it to be on par with a mid-drive motor system in terms of giving consistent torque on extremely steep hills. Other benefits of the Xion drive include a sophisticated control panel, regenerative brake assist, a quick release rear hub, and one of the most smooth performing torque sensors on the market.

The new Electric Bike Kit Owners group on Facebook has taken off within the first week of its creation. Around 400 people have joined the online group with new members being added every day. E-bike riders are sharing the various ways that they have converted their bikes using the E-BikeKit Complete Electric Bike Conversion System. Each one of the electric bike conversions is more unique than the next. Some e-bike…

Bike conversion kit usually includes an electric bike motor,a motor controller,throttle and brake lever,battery and charger is optional.The most popular electric bike kit package consists of 250 and 750 watts electric hub motor,36 volt 10 amp-hour lithium LiFePO4 battery,and 2-amp charger.

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.

Just kidding, here’s a little more detail. 1) Yes, actually you could just use one strip of nickel on series connections to make the electrical connection, but one strip of 0.15mm thick nickel strip can only safely carry less than 10A. Ideally you want at least one strip for every 5-7A you plan to pull through the battery. 2) You can definitely do the series connections first, it is just habit for me to do parallel connections first. Also, on larger packs I like to do parallel groups first and then glue them together and do the series connections as I glue each group. 3) People have explored this idea a bit on Endless Sphere, and while it can be done, it has a lot of room for error, mostly in keeping the spring loaded contacts permanently against the cell terminals and in keeping the contacts from corroding. Spot welding is the best method, in my opinion.

my questions are obviously related to sla’s as this is what i have now but if answers differ according to battery chemistry i would like to know this as well for future reference any info much appreciated cheers craig

Now you’ve got all the info you should need to make your own electric bicycle lithium battery pack. You might still need a few tools, but at least you’ve got the knowledge. Remember to take it slow, plan everything out in advance and enjoy the project. And don’t forget your safety gear!

The stokemonkey is only for long cargobikes like the Yuba Mundo, Xtracycle Edgerunner, and Surly Big Dummy, but…if you actually haul cargo, this drive absolutely conquers hills when you are fully loaded. They are still available in the classic edition (where the pedals turn when the motor is running) but now…they also have a freewheeling crank option. This system has recently been upgraded, and is now sold by ebikes.ca

Hi Joseph! Sorry for the confusion… I realize it can be overwhelming when you really dig down. Two things come to mind for you regarding a good mid-drive system available after-market and the internal shifting question.

The Dapu geared hub motor is made by a Japanese company in Shanghai, China. The Dapu motor is a geared hub motor. This motor type is distinct from a direct drive motor like Bionx, and has a variety of benefits stemming from its design that can be appreciated in its unique ride feel and performance. Geared hub motors work by transmitting power from a high RPM motor to the slower RPM wheel through a system of planetary gears. Because of the physics of electric motors, this “gearing” allows for higher torque and efficiency from the motor. Thus, the ride feel of a BH Neo bike is extremely sporty with consistent torque, even up
