Frankfurt-based manufacturer Lax Cycles is launching the Lax One, a versatile mini cargo bike. After five years of development, the award-winning city bike, which is manufactured in Germany, is now on sale.

With its compact overall length of 1.60 metres and 20-inch wheels, the Lax One is designed to be manoeuvrable and easy to transport. At the same time, it offers space for loads of up to 20 kilograms thanks to a generous front carrier measuring 40 × 33 centimetres.

Versatile drive options

Lax Cycles offers the Lax One in three drive variants: As a classic compact cargo bike, optionally with 10-speed derailleur gears or a belt drive, and as an e-bike with electric assistance. The Lax One e-bike weighs 19.5 kilograms and is equipped with a 250 Wh battery in the down tube and a 40 Nm hub motor.

An optional range extender with 160 Wh capacity can be mounted in the bottle cage and increases the range. The drive system uses a dual-torque sensor which, according to the manufacturer, analyses pedal pressure, cadence, speed and motor feedback in real time to provide precise support.

Lightweight muscle bike with belt drive

The classic version of the Lax One without a motor should weigh just under 15 to 16 kilograms. So if you are (still) fit enough, you should be able to master bends and climbs without motor support thanks to the low weight and agile riding characteristics.

The 10 gears of the Shimano derailleur system or, optionally, a low-noise and low-maintenance Gates belt drive in combination with a Shimano Alfine 8-speed hub gear help with this.

All variants of the Lax One are based on the same twin-tube frame, meaning that any classic bike can later be converted into an e-bike - and vice versa.

The Lax One Belt Drive version has an Alfine hub gear and a Gates belt. This makes this version extremely low-maintenance and suitable for everyday use. The Lax Bag made from recycled polyester is water-repellent and holds 55 litres of payload.Photo: Lax CyclesThe Lax One Belt Drive version has an Alfine hub gear and a Gates belt.

Equipment suitable for everyday use

In order to optimise the Lax One for everyday use, Lax Cycles has invested in the equipment. The front brake is equipped with four brake pistons and is therefore designed for use with a full load.

To expand the storage space, the manufacturer offers the Lax Bag with a capacity of 55 litres. The pack sack made from water-repellent, recycled polyester is attached to the front basket with a strap system. An extension to the Lax Doggy Bag for the safe transport of dogs and other four-legged friends is being planned.

Awards for innovative concept

The Lax One concept has already won over several juries. For example, the bike was honoured as the Gold Winner in the e-bike category at the Eurobike Award 2024. The jury praised the versatility of the concept and the riding dynamics of the Lax.

The Lax One also received an award at the Design & Innovation Award. The 19-member jury particularly emphasised the combination of load capacity, agility and aesthetics. Most recently, the Lax One concept was also recognised at the Cyclingworld in Düsseldorf won the Gold Winner award in the "Best Classic Urban Bike" category.
