I like unusual vehicles and I like bikes, so I got interested in Dodge’s crazy concept bike (4 wheels and a 500 HP engine) quite a time ago. I wanted to build smaller, not motorized version earlier, but I eventually focused on a medium-sized motorized model.
The goal was to make it driven remotely, with full suspension, and looking as accurate as possible. Steering turned out to be impossible – the real bike has left and right wheels suspended independently, and is steered by tilting left / right. With the LEGO model, it became apparent that both front and rear suspension needs a solid axle connecting two wheels in order to maintain the proper stiffness. Since there was no place for another motor anyway, I decided to give up the steering completely.
The model was eventually not entirely accurate, but it maintained the size and the silhouette of the original vehicle. All electric and almost all mechanic parts were covered up, the model was fitted with front and rear light and an integrated on/off switch. I liked its look and I consider it an interesting experiment, even though it was not so really fun to drive only straight ahead 🙂

The drive system. It’s just a single PF Medium motor.
What is the dive system?
@Mihály Stépán
They are pretty strong, but not stable enough to keep the wheels straight without a common axle between them.
@lego+car= 😀
You have to look at design and proportions here .. I think it is very well done in respect to these. It couldn’t be done any bigger since 8420 wheels are the biggest available, so no that much room for “technicalities” here
@lego+car= 😀
C’mon, can you build such a “rubbish” yourself?
its a bit rubbish…
its so bad it doesnot have steering!
How strong are those wishbone suspension arms?
@Mihály Stépán
No, I don’t think so.
@RjbsNXT
The space between rear wheels is 3 studs wide, it’s just enough to fit some bevel gears in some bracing in.
It looks like it could be the Bat bike
One question I’ve had since I first saw this model is how does the gearbox work in the rear axle? – there isn’t much space.
😛 And I forgot to say what I really wanted: great model!
I just had a crazy idea. Do you think if you made a motorbike, and if you drove it fast enough, it’s stay up and going? (Put aside difficulties like 2 motors in a bike, steering etc…. )
Hi 🙂 great design. the proprortions look quite the same as the original. I still have not understood whether the original model could steer or not …
Nice looking model! The black and blue colors are great together, and nicely portioned on this one. The suspension is cool. Really liking the links to the front wheel.
I like how you put the headlight and rear light between the wheel, also too bad for the steering 🙁
