    Heavy cargo hauler project

    That is my thinking, at least. It just might. A GPS tracker would be handy as well. I'm not at all sure. Some of it, if I'm lucky.

    Heavy cargo hauler project

    She was stolen from the driveway last night. Locked & 200lbs. It takes a substantial pair of bolt cutters, 2 guys and a dedicated transport vehicle to do, so it seems I'm a victim to professionals. I have zero hope of seeing it again. a couple hundred hours and 4500 dollars lost. Time to...

    Heavy cargo hauler project

    Just popping in to say Hi! I'm chugging along on new wheels. JRH heavy duty spokes Zinc plated and powder coated 2" moped rims with 2.5" Pirelli moped tires. It is a solid performer throughout. But I must admit that I'm pining to make a new cargo box. It should be longer, enclose the front...

    Radial lacing a no-no on hubbies

    I've given a stock 9C 2812 20' 14ga radial lace a thorough beating and I can attest that radial lacing did NOT work out for me common 700 lbs cargo loads in a 72v45A infinion setup. Tons of torque, lots of weight. At the one year mark the spokes started making squeaking noises when activating...

    Heavy cargo hauler project

    Bikes are stolen, sure. But mainly lycrabait and DH branded stuff. My gigantic cargobike with a locked, reinforced flightcase for cargo bay is not at risk unless you have a flatbed getaway vehicle and two strong men to lift the damned thing. I have locks on both wheels and a locked compartment...

    Heavy cargo hauler project

    Linkage steering on a 200 lbs, 8 ft long bike with a weird split saddle tends to draw lots of attention, but few people willing to test ride it when given the chance. And I reckon you are right... red hub and red rims will look good together

    Heavy cargo hauler project

    Time for an update of sorts. The old bike has seen lots of use, but a month or so ago, I started losing spokes on both front and rear wheels. I used the stock 16" 9C 2812 wheel, and the radial lace with the 14ga spokes has started failing after a good year of heavy cargo duty at 79-80V. The...

    Reclaim the Production - Open source vehicles

    Stumbled over this open source cargo trike video and thought I'd share: http://vimeo.com/64128185 website here: http://www.n55.dk/MANUALS/SPACEFRAMEVEHICLES/spaceframevehicles.html Seems like a pretty neat concept. No welding needed, built from commonly available square tubing, and you just...

    An interesting designer portfolio case example of e-bike

    I like the design! As a cargo nerd I must say I quite enjoyed the storage bin concept. Very practical, that :) Edit: I'd love to see this adapted to a more upright seated cruiser/chopper concept.

    Anyone know/own this carbon ebike?

    I hate being a Debbie downer, but I find CF to be a questionable material to construct bikes out of, let alone ebikes with their atypical stresses and strains. Be careful out there! old site, but bone chilling stories

    End of the World. Beginning of a new one. The Life of Amberwolf.

    My condolences Amber. Hang in there buddy! I understand you dabbled in home recorded music? If so I'll help get you back on 'track' hardware wise once the house is rebuilt. -Tom

    Your Job/Occupation/Career?

    There is always mass grave duty for the UN, but I'd hate to spend my life away from family and friends. My Father did that pursuing his career, and I've vowed never to let that happen to my own children.

    Your Job/Occupation/Career?

    I'm a forensic anthopologist by trade. Love the field, but I quit halfway through my stateside PhD due to the realization that my home country has no career prospects in that particular field. I then did some archaeology grunt work to pay the bills for a few years and finally started an...

    Brakes

    I'd like to get people's opinion on a brake conundrum: - I have a heavy 2 wheel bakfiets style cargobike. - Front 9C disk compatible front hub, but the non-standard front fork is too narrow to allow for a disk, and my cargo box prevents installing rim brakes. This leaves me with regen, which is...

    salinity gradient power plants.

    Seems rather counter intuitive to me, but it apparently works well enough that the Norwegians are building a full scale power plant. http://www.youtube.com/watch?v=Oc5bXa5PcWo Good stuff. -Tom

    2.5kWh + ebike?

    Cargo bike duty ftw. I currently have a 2'x2'x1.75' empty cargo hold and nothing in my frame triangle or on/next to the rear wheel. The lockable battery compartment holds 1.5 kWh ping + charger and controller, and has ample room for my bike helmet as well. While I have no need for added kWh, I...

    What is the strongest motor for hill climbing ?

    Using a 2812 in a 20" front wheel I have been able to lug a quarter tonne up a 10% hill at about 17 mph and moderate pedaling. Battery pack is 72v, 20A and I was outputting about 2.3 kW of power. the 2812 is slooow, but does cargo duty really well. I am unable to tease more than 1.5 kW out of...

    Kewet be? A Blast from the Past?

    I've test driven one of the 1992 models in our electromobility lab at uni. It is like driving a stripped down Mercedes smartcar. Ugly as sin, but made from glass fiber and steel tubing, so very simple to do home repairs on. The pre-norwegian models routinely show up in our local craiglist...

    Portable Ebike Solar Charger - build log

    I'm keeping a keen eye on this as my cargo bike has TONS of surface for this kind of thing :)

    Heavy cargo hauler project

    Charging completed. All hvc LEDs lid up within a span of 10 seconds. So to debrief: - brand new bms failed to initiate recharge operation after one successful cycle. - Initial attempts consisted of checking and rechecking integrity of charger and continuity of wiring. - I then cut the top of...

    Heavy cargo hauler project

    Red on gate, black on b- : voltages read 5.9 ish volts. The only thing I did was to move the bms pcb around for testing. There has to be an intermittently open circuit somewhere for the results to change like that. Its driving me crazy! The old one will get fixed afterwards.. I owe it to...
