exodyne electric motorcycle fuses battery power with home-made engineering

like a jacked-up battery pack connected to two wheels and a handlebar, the ‘exodyne’ electric motorcycle fuses rapid power with energetic, home-made engineering. created by a veterinarian in atlanta, usa, alan cross’ bespoke bike is the result of nine months of research, design and fabrication work. its center box frame, which houses 48 lithium polymer battery cells in a 100V 32 configuration, connects directly to the head stock with a swing arm pivot point. combined with a rear hub 11 kW motor, it has a top speed of 60 mph and a total range of 20 miles.

from the defining central battery pack frame, bright yellow scaffold-like structures shoot out to support the seat, as well as the rear suspension. alan’s craftsmanship has also lead to the reuse of machinery from old motorcycles. this includes; a 2005 suzuki ‘RMZ 250’ front fork, 1995 suzuki ‘RM 125’ headstock and rear swingarm, warp 9 wheels, brembo front brake, and a suzuki rear brake. interspersed between this upcycling, ‘exodyne’ is fitted with carbon fiber to ensure a low kerb weight of just 249 lbs. up top, the motorcycle is complete with a small cycleanalyst heads up display that shows its mph, amps and total discharge, as well as other essential information.

  • Hi,

    do you really think that these 4 screws connected to the centralized battery frame can support the suspensions system and force which will be produced during the ride?

    I do not believe.

    this idea requires a lot of improvements.

  • Nikola, of course not.
    But he made a concept bike. Can be well worked from here.

    Vasco Faria says:
  • Screw functionality. The thing is beautiful. If it doesn’t work it would be a great piece of static art next to the Giacometti in your living room.

    Ben Ross says:
  • Drop the over priced and wholly unnecessary ohlin shock…and make it for the masses, think Model T Ford…not expensive design lead impractical exclusivity for the few..

    Richie Rich says:
  • Bolts….Nikola.
    And where is yours……

    Rob Reynolds says:
  • Bolts…not screw .Nikola.
    And where is yours……

    Rob Reynolds says:
  • Very aesthetic concept, loved the frame curves and clean design.

    ziman says:
  • No fenders… Very low center point..Hydraulic reservoir, on top of handlebars ,( huh) ?
    A good starting point..

    Ron says:
  • Dear Vasco,

    Thank you for your open answer.

    I agree. I do have basic knowledge in Transportation design, but I would be more than happy to contribute to your project as the life style ID designer.

    Dear Rob,

    Thank you for your very constructive comment.

    best regards,


    Nikola says:
  • Hi Ron, the ‘hydraulic reservoir’ is for the front brake master cylinder.

  • Hi Rob
    Very impressive concept bike. I’d buy one if the price was reasonable.
    Only things are, I think the battery ‘cage’ needs to be a full tubular trellis to provide enough rigidity for the front and rear ends to attach to (especially as there is no big, solid alloy i/c engine to aid rigidity) and the rear swingarm looks like it needs some bracing.
    Oh, and finally, I’m not sure it needs the tank-esque shaped tubing at the top. Braced, straight tubes are more rigid and there is no practical or aesthetic reason for using curved tubing.
    I’m not trying to put this down because I think it is an amazing ‘think outside the box’ concept and that is what we should be doing in this age of technology advances. I’m just trying to give, what I think are, some constructive ideas.
    Good luck!
