HOW IT WORKS

What happens when you join the 10k+ happy Huckleberry Customers

order your bike

When your order your bike on our site, it notifies us at the shop.

Day 1

We'll build it and put it in a box

After you place your order, we'll build your bike – so you don't have to. Derailleurs, brakes, and every bolt is adjusted properly. From there, it's time to ship.

Day 2

Your new bike arrives at your door

We ship new bikes 95% assembled.

It takes 3 simple steps to get your bike rolling: 1. Mount the front wheel. 2. Attach the handlebars. 3. Put on the pedals

Day 4-9

Ride!

It's time to get rolling. You have a new bike to ride.

Day 9, 10, 11, 12, 13... every day.
