Hi Eric! It looks cool, I was just over at their site exploring but unfortunately I can’t comment on performance… Haven’t seen or tested one myself in person but maybe someone in the forums has and can chime in? If you end up getting this kit I’d love to hear your thoughts and feedback and in the mean time I’ll keep an eye out and try to get a review done 😉
Based on everything you wrote, I believe that http://huntneqip.com the Bosch or Brose motor system would be a good fit. I have owned one of each and appreciate their wider cadence range. You get shift sensing with Bosch but it sounds like you understand how shifting works given your nice carbon road bike… the Brose is a bit quieter and gentler feeling. Perhaps it comes down to which models appeal to you and fit your body size. I didn’t see your height there? Either motor system would be capable of moving your standard 165 lb body.

I want to use my two 4Ah Ryobi lithium batteries 18volts in series for 36 volts. I have a charger for them , they use 15 batteries each so 30 total, they are $50 each. This seems similar to your 36v build for about $3 each so $90 total, plus a spot welder for $1oo. I want to get a 38v/750 48v/1000w rear motor recommended from your web site from aliexpress. Do you think that these will work for my bicycle?
eBay determines trending price through a machine learned model of the product’s sale prices within the last 90 days. “New” refers to a brand-new, unused, unopened, undamaged item, and “Used” refers to an item that has been used previously.
Should the voltage on the charger be exact, or can it be *higher* than my battery pack? For example, I need to charge a 19.2V pack. Does my charger have to *exactly match* (or come as close to as possible to) this 19.2V, or can I use a higher voltage charger, (say, 36V)? Will the charger automatically adjust to a lower voltage, allowing a 36V charger to charge my 19.2V pack?
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.

I have built a few 13s lithium batteries in the past year following your instructions. Thanks. I have taken one of the batteries apart to check its condition as it is the middle of winter here in Winnipeg, Canada. Two parallel sets were out of balance with the rest of the pack. I was wondering if there is a way to use my imax b6 balance chargers to rewire the battery and keep each parallel pack in balance for sure! This way I will bypass the bms. Does this make sense?

Now that you’ve got an understanding for what a hub motor is… let’s talk about the benefits, drawbacks and ride quality. Hub motors tend to be peaky vs. torquey meaning they operate best at medium and high speeds. This makes them zippy and satisfying no matter which gear you’re pedaling in but less efficient over a range of speeds, especially slower ones. For example, if you’re starting from rest going up a hill and try to accelerate with a hub motor, it may struggle and even shut itself off. Here’s a short video I shot with a smaller 250 watt hub motor climbing a hill to demonstrate this.
As of August 1st, 2015, every E-BikeKit and E-TrikeKit will now include a set (8 x guides and 14 x zip ties) of Flexroute Guides and Cobra zip ties. These items are being added at no additional charge. Packs of these guides and specialty zips are also available for sale in our online shop.
It’s best to try and match the cells as closely as possible based on capacity by using a lithium cell tester like this one. If you plan on using the battery you build for a high drain application, different current ratings will be more of an issue. If you have many cells in parallel and will only pull low current from each one, then different current ratings are less of an issue. It’s always best to use perfectly matched cells, though I know that’s not the cheapest option and is outside of the budget for many.

Hi Derek, most engines produce a bit of drag when power is not being exerted because the pistons are still rotating (unless you shift into neutral) and this is why large trucks downshift to “engine brake” down hills. Electric motors are different and don’t produce as much drag, instead, direct drive gearless motors possibly like the one you rode with create a bit of “cogging” which is the staters repelling the magnets inside and this resistance can be increased by actively generating and storing electricity like a little power generator using regenerative braking but most electric bikes don’t offer this. Some motorcycles and higher-end ebikes do but most light weight low speed electric bicycles opt instead for standard brakes… usually disc brakes that do offer enough power to stop but require the user to apply them actively (usually the brakes also cut power to the motor when pulled for safety). I hope this information helps to guide your use of the mobility scooters and I wish and your wife you safe riding! It’s difficult for me to be any more detailed with feedback as I do not know the exact vehicle you’ve got and may not have tried one similar.
I should really change that $2 cutoff to more like $2.50, which is more reasonable for quality cells. Basically, the cheapest ‘good’ cells are Samsung 26F cells, which can be had for usually around $2.50 – $2.90 if you are buying in any large quantity, like at least 100. Expect to pay more like $3.00 or so if you’re buying only 40 cells. 26F cells are also limited to 5A discharge though, so you’ve got the same issue as with the NCR18650B cells from Panasonic.
