This past July 1st we moved our location to Croydon, PA and doubled our space. Additionally we’re looking to hire at least 2 additional employees! This is all to support our expanding conversion kit business and to support some new business we have planned starting in September (more to come on that soon). We would like to thank every single one of our customers, partners, associates and fans for your…

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.

Riding an electric bike is a green form of transportation, No gasoline and exercising yourself.You could customize your own electric bicycle with e bike kit,and this bike diy can be done at home with fun.

There are different models of welders out there but most of them work in a similar way. You should have two copper electrodes spaced a few millimeters apart on two arms, or you might have handheld probes. My machine has welding arms.

The bigger decision for me is whether or not to go with a 29” or 27.5” wheel set. I believe Bulls in the US only offers a hardtail in the 29” size. There is a lack of information out there on the pros and cons for my particular application (i.e., 60/40 paved and rough dirt roads) specifically with regards to e-bikes. I know you prefer the 27.5 size as an “all-arounder”. At around 5’ 10.5” tall (barefooted) and 160 lbs, I most likely could find a good fit in either wheel size since Bulls offers at least three sizes in most of their bikes. Since I do not plan on commuting or doing much mountain biking, is one size better than the other for my rural mixed road use? Would there be any significant benefits with the larger wheels with regards to riding efficiency (i.e., less effort pedaling, improved battery life, etc.) or does the mid-drive motor make this mostly a non-issue? Not yet having ridden these e-bikes, my gut feeling is it may just come down to fit and preference. I would be interested in what you think based on your experience.

Once I’ve got all the cells I need checked out and ensured they have matching voltages, I like to arrange them on my work surface in the orientation of the intended pack. This gives me one final check to make sure the orientation will work as planned, and a chance to see the real-life size of the pack, minus a little bit of padding and heat shrink wrap.

Original Shimano parts guarantees that all components work perfectly for optimum performance and maximum safety and longevity. This Shimano Cycling small part is known as: IBBR9100B. It has a UPC of: …

Sir, Your article does not describe the different methods to activate and control the motors. Do you have a separate article that deals with that? I am hearing about throttle, cadence and torque sensors, and others. Where can one learn about that aspect of the bikes? Thank you.

Another type of electric assist motor, often referred to as the mid-drive system, is increasing in popularity. With this system, the electric motor is not built into the wheel but is usually mounted near (often under) the bottom bracket shell. In more typical configurations, a cog or wheel on the motor drives a belt or chain that engages with a pulley or sprocket fixed to one of the arms of the bicycle’s crankset. Thus the propulsion is provided at the pedals rather than at the wheel, being eventually applied to the wheel via the bicycle’s standard drive train. An electric mid-drive combined with a hub gear at the back hub may require care due to the lack of a clutch mechanism to soften the shock to the gears at the moment of re-engagement. A stepless / coninuous ratio gear hub or a fully automatic gear hub may reduce the chocks due to the viscosity of oils used for liquid coupling instead of the mechanical couplings of the conventional gear hubs.

First of all, NCR18650B cells cannot be discharged at 2C. Those are 5A MAX cells, and really you should keep them closer to 1C to keep them cool and happy. They are economical cells. They do better when in large parallel groups so you can take advantage of their high capacity without the downside of their low discharge rate. They are great cells, but not for low AH packs.

You’ve done your math correctly, http://twowheelev.com that “1000W” figure is largely arbitrary, and probably not the exact power level of the kit. Most 1000W kits I’ve seen use controllers in the 20-25A range, but it can vary greatly.

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.

i am building a 10s4p 36v 18650 battery pack for my ebike, what gauge silicon wire you recommend for discharge and charge wires, i am using 2.5 amp 42.5v li-ion battery charger bought from ebay(http://www.ebay.com/itm/281639749374?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT), and 10s 36v 30amp bms bought from ebay(http://www.ebay.com/itm/182247900118?_trksid=p2057872.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT) and 500w 36v controller.

The Stromer ST2 uses an exclusive hub motor developed by TDCM for Stromer that is being marketed as “Syno-Drive.” The Syno-Drive hub motor has a number of design changes that make it perform better, weigh less, and run smoother than any other drive system we’ve tried.

Also, the best method for adding an auxiliary battery would be to connect it when both batteries are full, or at least at similar discharge states. That means the auxiliary battery won’t have to work as hard transferring energy to the internal battery, as they’ll be depleted together at similar rates. And the diode in the auxiliary battery will ensure energy only flows one way (towards the internal battery).

Then I took the sense wire labeled B1 and soldered it to the positive terminal of the first parallel group (which also happens to be the same as the negative terminal of the second parallel group, as they are connected together with nickel strip).

trying to decide on an e-bike for a 15 mile, hilly commute. I’m a heavier rider. tested haibike with mid drive (loved it), and specialized turbo S (also loved it). It seems the mid drive does better on hills, which kill me. there also seems to be a big difference in price on the 20mph systems and the 28mph systems. for a heavier rider, is it worth the extra cash for the 28mph system?

1. The extra amperage that the battery could output isn’t wasted, it’s just sort of a safety factor. It means you aren’t stressing the battery to its limit. Also, batteries only get their full rated capacity at lower discharged. So you’re more likely to get the full capacity now than if you actually pulled 50A out of it.

As long as you monitor your pack voltage so you don’t go too low during rides, then yes that would work. You’d simply run your discharge negative wire straight from the -1 terminal of your battery out to your controller, instead of from your -1 terminal to your BMS’s B- pad. But that removes the ability for the BMS to cut off the current when the voltage goes too low, so you’ve got to watch for that.

Hi Miran! The Pulsar 250 watt hub motor sounds decent, for your short commute it could work fine and in my opinion front mounted hub motors are alright for basic city riding. They can change the steering dynamic and handling a bit but with a small motor like the one you shared I don’t think it would be a big deal. I really like the Bafang mid-drive but that will be very fast, powerful and possibly illegal where you live. Also, it might be difficult to install compared to the front kit. Here is one I reviewed that might be similar to your Pulsar: https://electricbikereview.com/clean-republic/hill-topper/

You mentioned that you made a discharger from halogens. Is there any reason not to just use a couple power resistors in parallel, like 2×25 ohm, 100w for a 13s6p pack? Do you know why it’s helpful to take it easy on the pack for the first couple cycles?
