BUYER ALERT
Beware of fake “official” websites
Shopping for an electric bike from Koolux? Some websites look official without being run by the brand. Before ordering, check the retailer behind the website.
TWO THINGS WORTH CHECKING
01 Real UK premises
Do they have a shop or showroom you can actually verify or visit?
02 Repairs & support
Can they service or repair your e-bike if something goes wrong?
With TrailSurge, you can check both.
We have a real Nuneaton showroom and repair workshop, with UK-based servicing, repairs and 12-month warranty support. We're here for you after delivery, too.
