Enthusiast turns cargo bike into ultra-efficient solar vehicle for Alpine adventure and beyond
The Sun Trip has to be one of the most grueling eco-adventures and rallies where e-bikes race against time for 100 percent solar recharging ability. The sheer level of raw testing of machines against the elements, with no support crew or vehicles during the expedition, is what makes this Alpine adventure reserved only for those who are deep in their roots of engineering.
The eco adventure requires the e-bikes to go through mandatory checkpoints via designated regions, or pick their own routes. There’s no scope for any repair assistance or night camping provisions. One rule that’s crystal clear is that you never touch grid electricity during the course of the competition; otherwise, you are disqualified for the solar leg. Since 2013, the event has run successful editions in Europe, Central Asia, China, and North Africa.
Designer: Shawn Boden Ryan
This year’s Alpine edition saw an interesting e-bike powered by a solar panel array mounted on the front of the ride. The man behind the build is Ryan, who took a salvaged Omnium cargo bike with a sizeable front rack panel and turned it into a solar-powered ride for the competition. The first task was to remove those big panels and make way for a very unique 200W solar power array connected to the Genasun GVB-8 boost MPPT single charge controller. This was then mated to the two 36-volt batteries – one of them from EM3-EV, and the other from Infinit. Doing the heavy lifting in the setup is a 250W Tongsheng TSDZ2B mid-drive motor from Varstrom.
Since the amount of energy generated by the solar panels is a premium, the setup runs perfectly in this configuration. Keeping the overall weight down to a minimum was essential; therefore, even with the camping gear, camera equipment, and other essentials, the bike clocked just under 135 lbs. The changing spectrum of weather during the course of the competition was a big challenge, as the heatwave proved to be a big challenge. One of his batteries – the Infinit modular – took the onslaught of 41 degrees Celsius. “The BMS was essentially doing its job and protecting the battery, but it meant that for periods of the day I couldn’t store all the solar energy the panels were producing,” Ryan said.
The handicap forced him to plug into the grid for 1kWh of energy harvesting, which automatically put him out of the solar-only competition. On the good days, the 200 W capacity proved enough to power his bike through, but scope for things going wrong was pretty thin. Even if the battery would not have failed, it was anybody’s guess if he would have managed to make it through the solar-only competition. That I say because Ryan himself admitted that, “250W Tongsheng did struggle thermally on some of the really long climbs.” Learning from those little outcomes, he is already redesigning the concept bike for the Sun Trip from France to China in 2028.
He is considering shifting from a cargo bike to a long-wheelbase semi-recumbent layout. The solar bike will have the rider seat considerably further forward, topped with the wide solar canopy. This will increase the solar area, boost the aerodynamics, and make the ride more comfortable over long distances.

Someone Just Built a Digital Camera That Ejects Photos Like Real Film
Every digital photo you’ve ever taken lives the same way, buried in a folder, scrolled past, forgotten within the hour. The Camera with Digital Film refuses that fate for its images. It captures a scene digitally, then commits that single shot to a small e-paper cartridge you can pull out, prop up, and actually look at, closer to a printed photograph than anything living inside a phone.
The trick sits in the cartridge itself. Slide it into a slot at the top of the boxy 3D-printed body, press the shutter, and a Raspberry Pi with a 5-megapixel camera module does the capturing. The e-paper screen inside that cartridge then flickers and settles into a finished image built from just four colors, black, white, red, and yellow, giving every photo the flattened, graphic quality of a screen print rather than a snapshot.
Designer: Jens (Strange Inventions Lab)
That four-color limit isn’t a technical shortcoming so much as a deliberate constraint. Before the image locks in, a script reduces the raw capture down to that palette while letting contrast, brightness, saturation, sharpness, and dithering get tuned until the picture actually looks intentional on a screen that small. The result rewards patience over speed, closer to darkroom fussing than instant gratification.
Pull the cartridge free afterward, and the photo doesn’t disappear. E-paper holds its image even with the battery removed, so that little rectangle becomes a physical object you can lean against a monitor or stick to a fridge door, exactly the kind of permanence chemical film offered and most digital cameras never bothered to replicate. Slide it back in later, though, and the same cartridge accepts a brand new shot, erasing the old one entirely.
That’s the real design move here: film that behaves like film until you decide otherwise, then behaves like a hard drive instead. No single cartridge is precious in the way a Polaroid frame is precious, since nothing is technically lost by overwriting it, yet each one still holds its picture with enough physical weight to feel worth keeping around for a while first.
The build itself skips screws entirely, relying on header pins to hold the cartridge snug against its contacts, with a small grab tab added later so removing a used cartridge doesn’t turn into a fight. It’s a minor detail, but one that matters for a device whose entire personality depends on how satisfying that swap feels in the hand, less like ejecting a memory card and more like pulling a photo out of a machine meant to produce them.
There’s a quiet argument buried in this project about what digital photography gave up along the way. Endless storage solved scarcity but erased the ritual of a photograph actually existing somewhere outside a screen. This camera doesn’t try to out-spec anything on the market. It just asks what happens when a picture has to earn a place in a slot before it’s allowed to disappear.
