What is a prototype?

A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:

Proof of Concept

Explorations that test ideas and functionality.

Functional Prototype

Demonstrates the functionality of the final product, but looks different.

Appearance Prototype

Looks like the final product, but is not functional.

Design Prototype

Appearance and function match the final product, but is made with different manufacturing methods.

Production Prototype

Appearance, function, and manufacturing methods match the final product.

The House of Mohist presents: 
"Solar Basket: Universal Solar Upgrade Kit"

Bring a little sun in your life...

Everything in the basket
Everything in the basket

Our Story

The whole project started as a challenge to build an autonomous vehicle for home usage. Instead of start with AI and vision system, we started with energy system. Self managed and self energy sufficient mobile platform, large enough to be useful and light weight enough to be safe, that pretty much let itself to the solar bike/trike territory. We envision an affordable, clean energy system that would provide transportation, power/energy, wireless communication, data, internet and security to people everywhere on earth. Solar Basket is the first commercial component of our grand vision, and with your support, a better and brighter future awaits. 

Our design philosophy

  • Flexibility: Connect various battery types with Boosted MPPT Solar Controller to charge 24, 36 or 48 Volt Bike battery with a single panel
  • Simplicity: Quick plug and play using the Standard MC4 Connector
  • Scalability: Very simple to add extra solar panel for more power or convert your solar e-bike into an emergency energy source 
  • Affordability: The whole system cost less than an extra lithium e-bike battery
  • Open Source Hardware

 This is the solar everything conversion kit. We designed this pack to take  portability and design flexibility to the next level. Take the kit with the bike, or put it in your backpack, make it part of your tent, patio cover, window shade,  beach chair, sun umbrella... There is nothing to tie you down. Panel itself has regulated 5V, 12V, 19V output, combine with the adjustable 15V-90V output of the solar regulator. Nearly all DC electronic appliances could use more efficient DC-DC conversion, instead waste energy on DC-AC-DC conversion. Charge your cell phone; charge your laptop; charge your car, boat battery; power and charge 12V or higher DC powered blender, refrigerator, electric lawnmower, powertool, Roomba, Hoverboard... You can also connect panels together thru MC4 cables to expand energy capacity. The possibilities are endless.

60 W folding Solar Panel make it easier to take everything with you.

This is your off-grid, camping, disaster preparedness energy source, solar starter kit. Minimal installation, find a sun facing window, door or patio, hang up the the flexible panel, connect the wire and instant electric outlet. 200 watt AC inverter let you power your small electronics when the whole neighborhood goes dark. 220Wh/20,000mAh lithium-ion battery will keep the lights on in the dark. When the sun comes out, recharge your battery pack with the 60W solar panel. The whole generator fits in a portable, light weight package, so you can take it everywhere.

  • Weight: 5.5 pounds
  • Dimensions: 9.8 x 6.3 x 3.4 inches
  • Battery Capacity: 220Wh/20,000mAh
  • AC/DC Output Wattage: 200.00

Risks and challenges

There are thousands of different electric bikes out there. Each one has its own unique design and configuration. It is very likely the solar basket we designed would not fit the some bikes. We have made the individual components as flexible as we can, but some extra tooling and retrofitting might be required.
