Created by a group of students from different countries, to try and bring a durable and capable e-bike to our streets, the result of their collaboration is the Sudaca.
Now, it doesn’t look complicated at all, and like all good things, it isn’t. What initially struck my visual cortex was that ‘fuel tank’ on top. It’s not really a fuel tank. Actually, we don’t know what it is. But seeing as how this is an early model e-bike, it seems a good design aspect to keep if you’re trying to target and convert existing moto riders.
We then see the huge exposed tube frame. Once again, the design leads me to think it’s meant to be like a motorcycle as much as possible. You know, maybe I'm being too harsh on this design. Maybe I've been approaching this whole thing from the wrong perspective.
Like an EV, the two most important components are the battery pack and motor. As far as the battery pack, it's that big black case underneath the fuel tank. The initial design is constructed around three 12V lead batteries. But the boys thought ahead a bit and made the case suitable for more powerful lithium ion batteries.
The motor we can see at the rear of the bike. That drum-like object is an in-wheel brushless 0.75kW motor. Sure, it may not seem like much, but the technology back in 2014, accessible to university students, wasn’t what it is today. But the guys thought ahead again, and the Sudaca is able to be fitted with a 12kW motor.
Looking at the front of the bike, we again get the impression of a heavy-duty motorbike. A huge front fork and a handlebar set-up reminiscent of motorcycle design leads to a fat-tire set-up with disk brakes. We don’t see a braking system on the rear of the bike. But I can bet that as you release the throttle, the motor starts to brake.
To top off the design, we find a pair of splash guards to keep things dry and clean, and a couple of LED head-lights, and a kickstand. Nothing complicated, just a solid design for an early EV that we may have overlooked.
