Mini Bike Fest Berlin #1: Small Bikes, Clever Cargos
The Mini Bike Fest rolled back into Berlin for its second edition, and what a feast for tiny-bike lovers! I made it there just in time to photograph some incredible mini creations on display that day, and we’re kicking off a three-part series, with this first instalment focusing on three standout cargo bikes. Each one is more inventive than the last, so let’s dive in!

Kata built this remarkable bike as part of the Bespoked x SRAM Scholarship in 2025. Coming from an XS Omnium cargo, she felt the fit wasn’t quite right, and like many cargo bikes, it also carried more heft than she wanted. That led her to reimagine what a light cargo bike could be: one that fits her perfectly, feels more responsive, and still delivers practical everyday utility. To bring that vision to life, she opted for smaller-diameter tubing, an aluminium steerer tube, and a carefully chosen mix of carbon components, including a SRAM Atmos carbon bar, a Zipp SL seatpost, and a Tune Speedneedle saddle. I have to mention the lovely paint job with plenty of little details to look at and the “Dog Box” made by Gramm!

A second standout cargo creation comes from a vintage CATS frame, an old German MTB brand that began life as a 26-inch mountain bike before being transformed into a 20-inch cargo bike. Most of the tubes and lugs have been preserved, with only the angles altered, while the beautifully segmented rear end is a brand-new addition. Up front, a BMX fork has been adapted, and the removable rack system can be taken off with just six bolts.
The goal here was simplicity: reuse as much of the original tubing as possible while creating something functional and distinctive. I’m a big fan of all the thoughtful little details, from the light mount to the Hungarian forints used as bar ends.

Joystick Stem and "mystery" handlebar.
Wheels
Alligator 16” rim with a front dynamo hub and a rear Shimano 3-Speed.
This is the grown-up version of the Mini Cargo the team at Endless Bikes built a few years ago. To make sure it could handle the full weight of an adult, they had to add an extra pair of seatstays, and the result is an absolute little wheely machine that’s a blast to ride on these Schwalbe Big Apple 2.1-inch tires, even if the small wheels can make it feel a bit wobbly at speed.
It’s also packed with clever details, including a raised bottom bracket, a NASCAR-themed paint job, and, of course, a dynamo hub paired with lights. As Elias put it: “We’re a city bike shop, and I don’t think we ever built a bike without a dynamo hub.” Can’t go wrong with that statement.
