    Build your own DIY fat tire electric bicycle for just $600

    The first thing you’ll need is a basic level of handiness. You don’t have to be a mechanic, but as long as you’re comfortable turning a wrench and have the necessary skills to swap a flat tire on a bicycle, then you’re probably ready to build your own e-bike.

    Next, you’ll need three basic components:

    • Fat tire bicycle (the donor bike)
    • Fat tire electric bicycle conversion kit (includes everything except the battery)
    • Battery

    Did anyone notice that 1 kW hub motor (non-street legal BTW) is laced to the fat rim using a radial or zero-cross pattern? Really bad idea. One has to wonder what the manufacturer was thinking, or if they were thinking, or if they are capable of thinking. Should be an interesting way to see how good their customer support is though....

    EDIT: BTW, that radial-laced hub motor/wheel is intended to go on the front of the fat bike along with a disc brake. So it will see big torque in both directions. Any bets on how long the spokes last?

    It’s super hard to do a cross spoke pattern with such short spokes; the hub is huge and the angle gets all extreme where the spoke enters the rim. Radial laced was maybe not the best idea though...

    This looks really nice. Do you have a estimated price for the conversion? I assume used battery packs. What do you use to charge it?

    Hey,

    The estimated build cost was about $4,500.

    It actually is a "used" battery. but I believe the Nissan Leaf these cells were removed from was totalled in an accident with less then 7000 miles. Therefore lightly used, and only $800 for the pack.

    I use "Meanwell" DC power supplies to charge the battery. They are remarkably durable and powerful, IP65/67 waterproof, and adjustable voltage and amperage. With the Meanwell "HLG-320" series I used 2 wired in series for a 640 watt charger that sits neatly under the bike's battery. There are also 2 cooling fans that draw heat away that are powerd by the small Meanwell LPV-20-12 unit. this supplies 12V 20W from the charge port of the bike. So when plugged in the fans kick on automatically.

    The Meanwell units can be wired in Series and/or parallel to provide for additional voltage and current needs. Search "HLG-320H series PDF" and you'll know anything you'll need to know about these things.

    In my case I used 2 "HLG-320H-42A" units wired in series. I adjusted both to 45.5V for a total of 91 volts. The battery is charged to 89V when full, the extra 2 volts helps push current until the end.

    Iconic Honda Super Cub is back, and this time it’s electric!
    Micah Toll

    The Honda Super Cub is a legendary retro-styled motorbike that has been in continuous production since 1958. With over 100 million units sold, it holds the record for being the most produced motor vehicle in history.

    For all of its strengths however, the little retro scooter has one major downside: its internal combustion engine. Sure, it’s a gas sipper instead of guzzler, but it’s gas nonetheless. Until now, that is, as the Super Cub is finally being reborn as an EV.

    B6B05012-B3DC-4FB7-BDE0-2AFFB2A30B3C.jpeg

    To build the eCubs, the company starts with a stock Honda Super Cub and then goes to work on it, gutting the engine and gas tank to replace them with a 1,000 watt rear wheel electric hub motor.

    32605F61-C81C-4F8B-B54E-7712B595E02C.jpeg

    The eCub2’s range is 40 km (25 mi) at 45 km/h (28 mph) with a standard 80 kg (176 lb) rider. While that’s nowhere near the range of more conventional electric commuters such as the Zero electric motorcycle, it’s likely enough for most city commutes.

    7B9FA879-1DC8-4C4F-9078-D19B4EB6F4E4.jpeg

    For those that already own a Honda Super Cub (that would be millions of people, presumably), Shanghai Customs doesn’t want you to have to throw it out just to upgrade to electric drive. They’ve produced a conversion kit that will allow anyone to convert their own Super Cub at home and build a custom DIY EV Cub.

    I've been working on a HondaCB360T that a buddy gave me, oh 8 years or so ago. I have all the parts I need but between drag racing the electric Pinto, electric Mitsubishi, pit bikes, HawgTy's... cabin..... house.. life..... I just still haven't finished it. Stretched the swing arm 3" and swapped in CB750 shocks. This is how it sits right now. 20130630_205739.jpg CB360_a.jpg CB360_b.jpg

    not sure what diameter the headlight is, KC Highlights have some round LED options.

    We are plotting one out, have the rolling frame, still looking for low-cost (or free) components, as this is a budget build, community-based project.
    Made a cute video for the appeal.

    Hey guys,

    I've been building electric bikes for a LONG time and have a lot of used and leftover parts. Would you be interested in a "Motenergy ME0709"

    Power: 8 cont-- 19 pk hp
    Voltage: 72 Volt rated
    Speed: 3700 rpm @ 72v unloaded
    Size: 8" OD, 6.5" long (w/o shaft)
    Shaft: 7/8"x 1-3/4", 3/16" key
    Weight: 36 lbs.

    LINK-> https://www.electricmotorsport.com/...709-pmdc-motor-24-72v-8-hp-cont-19-hp-pk.html

    I blew up two brush packs in this motor. I realized I was pushing the boundaries of what this motor can handle and upgraded to a ME1003.

    I will mail you the ME0709 motor for FREE along with two brush-packs, both brush-packs have issues but you can piece together ONE good brush pack with patience. I will clean up the commutator before mailing it.

    Please let me know if this interests you.

    -Tony

    oddly I was not prepared for any assistance, just thought this might be a good place for ideas? Oh, and several local folks got a kick out of the video :) Normally I would say yes to any offers of free stuff, but we are limited (I think) to a 24 volt situation, as I have not been able to move anyone from lead-acid or AGM? Let me discuss with the crowd to see if we can do some re-engineering/re-thinking the design. In the meantime, thank you for your generous offer, and I hope to give you an answer shortly.

    My hesitation has been eliminated, we would LOVE to acquire this motor, after reading specs, we can run 24 volt on this right? Sending PM now. Thank YOU!!

    This is a great watch (the guy filming is just a little excited):



    R1 converted to a 176.4v race bike. Sweeet.

    Another way is to take an already electric bike and make it better. I just picked up via Craigslist a 2017 Chinese scooter with a measly 2000w 72v motor/controller. Over the next year or so I plan to upgrade it to be a 60mph/50mile errand bike. (In its current configuration it is limited to just 30mph/25miles). First thing to do was remove the decorations and strip it down to its bare essence:

    Next up is to replace the controller, swingarm, and re-wire her. Still evaluating different brands of controller. More to come in the next few months.

    I am really impressed with the results of your efforts. Totally transformed that scooter removing the decals.

    My personal experience on my longtail cargo bike is that short spokes cross laced to a large hub motor won't run straight, and end up breaking at the nipple. Haven't had any spokes break since switching to radial lacing even though I went from 12G spokes to lighter 13G spokes.
