Still have questions?
How long does shipping take?
As soon as you place an order, we will dispatch from our warehouse the same or next day. Delivery may take 1-3 days depending on your location.
I've ordered a bike. Will the accessories arrive together?
No, the items will arrive separately. Accessories are "brand new" products dispatched directly from our warehouse, whereas bikes are sold by individuals or other businesses, so the collection addresses will differ.

Yes! We offer a 30 day return window to give you plenty of time to try out the product and return to us.
Do you offer a warranty?
Yes! We offer 2 year warranties on all accessory products and parts sold by MyNextBike.
