An interesting technology startup that can produce a custom-fitted eBike to your exact body dimensions. ;)


The innovative Superstrata bikes are made possible thanks to novel 3D printing technology developed by Arevo. After developing a way to 3D-print carbon fiber in a much stronger and more robust form than standard carbon fiber layup, the team began searching for a product that could demonstrate the technology’s advantages. They learned how fragile carbon bicycle frames can be, and so the team enlisted award-winning bicycle-designer Bill Stephens to develop a bicycle that could be 3D-printed using Arevo’s technology.

As Superstrata CEO Sonny Vu explained in a call with Electrek: My friends were always so careful with their expensive carbon bikes, afraid for it to tip over or get hit. And I’d ask, ‘I thought carbon frames are super strong?’ but they’d respond, ‘No, they’re super light. But they can be fragile.’ And that is one of Superstrata’s big advantages, that their frames can take a beating in pretty much any direction, unlike most carbon bike frames that can crack or break if loaded or stressed in the wrong way.

Though that’s not Superstrata’s only advantage. Unlike most frames that come in a few sizes, Superstrata’s bikes are custom 3D-printed to the precise size of the rider. Customers simply provide their body measurements as if they were having a suit tailored, and Superstrata’s algorithm calculates and then prints the bike’s geometry customized for the rider in a true unibody frame — no glue, joints or seams needed like in traditional carbon bike frames. Even the preferred stiffness of the bike’s frame can be custom-tailored to the rider’s desires.

Riders can further customize the bikes by choosing from four different styles (racing, street, gravel, or touring), two-wheel materials (metal or carbon fiber), and two colorways (light or dark). https://www.indiegogo.com/projects/superstrata-bike#/

when you follow the link, the full article lists battery & motor details...
There are four occurrences of the word "motor" in the article and no motor brand or battery size can be found. Will you care to help me find the details?

Personally I would be less interested in an "infinite" number of sizes than I would be for more options of motors and whatnot. Can I have one with a hub motor mated to a Pinion gearbox and connected with a Gates belt? I realize that is not really practical from a production standpoint. But they are still really only selling one frame as far as I can tell, contrary to what the ad copy says. Maybe they custom tailor to size, and the size of the top tube, but there are no options for changing the wheelbase or geometry as far as I can tell. Touring is one option? Is there going to be mounts for racks or mudguards?

It's a beautiful bike. Where are you getting the only rear hub motor reference?

I think this is a beautiful design that deserves an integrated mid-motor with the Class-3 28 mph speed.

Limited specs below:

While the Superstrata Terra requires you to do all the work, the Superstrata Ion is an electric bike with a battery hidden in the downtube of the frame. Its 250W rear motor (350W peak) propels the bike up to a top speed of 25 km/h or 15.5 mph while employing a bottom-bracket torque sensor.

The bike is pedal assist-only, and thus the base model comes with a 36V battery rated for 125Wh of capacity, though the company has confirmed that a larger 250Wh battery is coming soon. Superstrata claims a maximum range of up to 35 miles (56 km) in the lowest pedal assist mode on the entry-level battery; however, e-bike ranges are notoriously wide and affected by many variables. One benefit of a small-ish battery and motor is that the bike’s weight remains extremely low at just 11 kg (24.2 lb).

Since that company specializes in the 3D printing of the frame and less on the complete bike, any manufacturer can request a frame that’s specific to a mid-drive motor (name your flavor - Bosch, Brose, Yamaha, Bafang) and build the complete bike for specific markets. Any volunteer bike companies out there? :)

Bullshit. If a respected motor is to be used, the bike must be designed for the motor and battery from the very beginning. Not otherwise.
