Buying Koolux online?
As with a car, ask where you can take your ride if it needs a repair.
Be cautious if a seller can’t give you a local workshop address, especially if they ship from overseas or dropship.
Check with the brand that the seller is authorised and ask who handles warranty repairs.
We serve NHS staff and fire and rescue workers, and support local police with e-bikes.
