A 700lb bicycle coffee trailer with dual Nine Continent 9C direct drive 1,000W motors that is towed behind a 1984 Kuwahara Shasta.
Scavenger Coffee is a mobile coffee shop that bikes around Vancouver. The cart is handmade from local and scavenged materials. The espresso is hand pulled on our 1970s Italian espresso machine called “Fantastiko”.
We've listed some of the build below, but there are so many details and hours and design considerations that went into this that it's impossible to share everything. Happy to chat if anyone has questions or wants to build their own e-trailer!

Brake Splitters & Lines
Since the cart is so heavy (700lb) we have three braking systems:
1. Front and back cantilever brakes on the bike.
2. Disc brakes on the trailer
3. Regenerative e-braking
We only have two levers though so we had to get creative on how to control all of that. The e-brakes kick in once either lever is pulled and the throttle modulates the intensity of the regen. The one lever was modded (based on a bike polo design) to work both brakes on the bicycle, and then the other lever ran a cable down to the hitch arm of the trailer where it splits into two long lines (thankfully tandem brake cables are extra long) that actuate the disc brakes on the trailer.
To route the lines we had to make a series of cable stops and bolt them onto the chassis to try and avoid having to run cable housing the whole way.

![We didn't have a TIG welder so we tapped our aluminum chassis and bolted on the steel cable stops.](/pub/media/project_gallery/projects/6800749c/fantastiko-coffee-trailer/brake-splitters-lines/brake-splitters-lines_3.jpg)
Hitch Attachment
Our DIY solution for a strong but flexible trailer hitch.
![The small bits of pipe keeping the rod-end bearing stabilized in the centre were scavenged from a busted bike frame. This was an earlier version, the final version uses multiple washers and a jam nut to keep everything tight.](/pub/media/project_gallery/projects/6800749c/fantastiko-coffee-trailer/hitch-attachment/hitch-attachment.jpg)
![We used angle iron, u-bolts, leather, and rod-end bearings. Design inspired by Haulin' Colin out of Seattle.](/pub/media/project_gallery/projects/6800749c/fantastiko-coffee-trailer/hitch-attachment/hitch-attachment_1.jpg)
Stamped end caps
It's the little things, like custom wooden caps for every aluminum tube.

Drop Outs & Disc Brake adaptors
We sized up a few times but ended up with these beefy drop outs that could handle the back and forth action switching between motor and regen braking.

![Getting these disc brake plates welded on in just the right spot was a stressful endeavour. I realized as I went to build more adjustability into the design e.g. oval holes for bolts and space for shim washers.](/pub/media/project_gallery/projects/6800749c/fantastiko-coffee-trailer/drop-outs-disc-brake-adaptors/drop-outs-disc-brake-adaptors_2.jpg)
Drop Down Wheel
Version 1 used bike components (seat tube, quick release, chopped up seatstays) to lower a caster wheel. The problem was that you had to strain to lift the cart with one hand and then lock it into place which was a great way to strain your back.
Version 2 was a chopped down trailer wheel (you can't buy them small enough). We pulled it all apart, cut everything (tubing, lead screw, etc) in half and then welded it back together.
![Made from an old bike frame and a caster wheel. This was also our first attempt at MIG welding rather than stick welding.](/pub/media/project_gallery/projects/6800749c/fantastiko-coffee-trailer/drop-down-wheel/drop-down-wheel.jpg)
![Chopped down trailer jack wheel. Although our stick welding got a lot better we also used bondo and paint to make it look pretty.](/pub/media/project_gallery/projects/6800749c/fantastiko-coffee-trailer/drop-down-wheel/drop-down-wheel_1.jpg)
