Woman wearing the Helsinki Pro Bike as a backpack, next to a man with the same bag clipped onto his bike rack

Kapten & Son · Helsinki Pro Bike

On the rack, then on your back, with no hooks sticking out.

The Helsinki Pro Bike clips onto your bike rack with two hooks and a lower rail. Off the bike, the Click & Go panel rolls up into the bottom compartment and the padded straps come out: it is a backpack again, with nothing sticking into your back.

Click & Go

From the rack to your back.

Two hooks clip onto the top tube of the rack and adjust sideways, with spacers you can remove; a lower rail that turns 180° steadies the bag.

The Click & Go panel unzips at the sides, rolls up and slides into the bottom compartment; the padded straps come out from underneath, and the chest strap clips across.

Off the bike, in four moves

Lift it off
Take the bag by the top handles and unclip it from the rack.
Open the sides
Open the two side zips of the Click & Go panel.
Roll it up
Roll the panel up, hooks inside, and slide it into the bottom compartment.
Take out the straps
The padded straps were underneath: put it on your back.

Kapten & Son

Clipped on, unclipped, on your back: a morning in town.

Eiken's take

Why we picked it: It is the Helsinki Pro made for the bike: on the rack for the ride, on your back at the office, without changing bags.
Good to know: It weighs 1.7 kg empty, 400 g more than the Helsinki Pro: without a rack, take the Helsinki Pro.
Who it's for: Bike commuters with a rack and a laptop.

Baptiste, Eiken

Questions

Helsinki Pro Bike: your questions

Another question? Write to us, a person answers: info@eikenshop.com

Will it fit my bike rack?

Yes, if it is at least 12 cm long, with tubes from 10 to 17 mm: the two hooks adjust sideways and come with spacers you remove if your tubes are thick.

Does my laptop fit?

Yes, up to a 15.6-inch PC or a 16-inch MacBook: the padded sleeve measures 43 × 29 cm.

Is it rainproof?

The fabric is water-repellent, and so are the zips of the flat and small front pockets; for heavy showers, the rain cover goes over the bag. It isn't made to be submerged.

Can it go in the cabin?

At 52 × 30 × 15.5 cm, it fits the usual 55 × 40 × 20 cm cabin allowance.

Care

Lukewarm water and mild soap on a cotton cloth, then let it air-dry. Never in the washing machine, never with chemical cleaners.
