Electric trikes have also been produced that conform to the e-bike legislation. These have the benefit of additional low speed stability and are often favored by people with disabilities. Cargo carrying tricycles are also gaining acceptance, with a small but growing number of couriers using them for package deliveries in city centres. Latest designs of these trikes resemble a cross-between a pedal cycle and a small van.
Actually I have ran into a problem – a few days ago I was riding it up a hill on a hot day when the power cut off and it wouldn’t start again. When I tried to charge it, the light on the charger just flickered from green to orange. I took out the battery and found that one of the cells had corroded from what looks like overheating. I think that the battery pack failure was most likely caused by too much of a load applied to the battery pack.
Electric Bike Conversion Kits are prepackaged sets of components designed to fit on a normal bike and convert it into an Electric Bike. These kits make it easier for end-users to find compatible, functioning parts and purchase them all together. A kit can range from a complete system that includes all the batteries electric scooter parts you need, to DIY kits that include only a few parts and leave the rest up to the user.

Another excellent answer, thanks so much! Now it has arisen a few related questions, if you don’t mind answering them. I’m using authentic Samsung ICR18650-26FM cells. I had already purchased a 24V 15A BMS before I slightly understood all of this. I was also able to obtain more cells since my original idea, so I was planning a 7S10P pack (around 30Ah), 70 cells total. I see each cell can do around 5A, making a 10P pack put out 50A total. If I stick with my 24V 15A BMS, that will give me 15A * 24V watts, or 360 watts total for my 500 watt motor. I’m going to number these to make it easier:
Spot welders for batteries aren’t the same as most home spot welders. Unlike the large jaw spot welders for home workshops, battery spot welders have the electrodes on the same side. I’ve never seen them for sale in the US, but they can be found pretty easily on eBay and other international commerce websites. My full time use welder is a fairly simple model that I got here. A highly recommended source for a slightly nicer spot welder design (pictured below) with both mounted and handheld electrodes can be found here.

I’ve had good luck with Bulls and Haibike but any frame manufacturer that gets to work with Bosch or Brose is going to be good. Easy Motion has a couple models now with Brose. If possible, try to buy from your local shop so they can fit you and offer warranty support. Do you know what brands they carry? I’d say, pick one based on pictures, special order the correct size and go in to pick it up… when you go, have the shop also order a riser or even rise + swept-back bar and maybe some ergonomic grips. Get a Thudbuster or BodyFloat or the Suntour NCX seat post suspension in the correct size and have them fit you. You could swap tires too but I love riding knobby tires even on the road, they a huge difference on dirt and it sounds like you spend some time on surfaces like that.
Hey Court – I would have replied sooner but I wasn’t notified you had replied, guess I will have to check this site more often. I never thought of a front drive system before, I will check it out. From what your article said, I think I can still pedal and probably need to to go up a 8% grade. I like the idea of being able to simply detach the battery and the hub when I put it in the boat. I am going to look around for a more powerful motor as I need to get it up to closer to 28 mph if possible. Just did the ride yesterday and let me tell you the whole way I was like, “need that ebike NOW” If you have any other thoughts let me know….. Thank you, Eric
Continue down the row of cells placing a weld on each cell. Then go back and do another set of welds on each cell. I like to do 2-3 welds (4-6 weld points) per cell. Any less and the weld isn’t as secure; any more and you’re just unnecessarily heating the cell. More and more welds won’t increase the current carrying ability of the nickel strip very much. The actual weld point isn’t the only place where current flows from the cell to the strip. A flat piece of nickel will be touching the whole surface of the cell cap, not just at the points of the weld. So 6 weld points is plenty to ensure good contact and connection.
You commented on the cost without commenting on quality or design or anything other factor. Not really fair. I can buy a house for twice as much as a another house, insane? Likewise you could find a car for twice as much as your current car – is that insane? Without examining the other variables (quality/features/etc) its not even reasonable to begin commenting on the cost.
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.
Wow. Thanks for the info. Do you mind if I ask more? How fast does the ST2 go? Does focus thron impulse (FTI) have the same torque as the ST2. The video mad e the ST2 look very good. what do I get from FTI that I don’t get from ST2 other than suspension? Is there a price delta? I have not looked at the other bikes you mention. Can you web site to a comparison of them all? I really want to buy before summer. Thank you so much for the info. craig
