KirbEbike sells ebike conversion kits that turn a regular bicycle into an electric ride — off-road, commuting, fat-tire and road-legal kits from 500W up to 2000W, plus batteries and mid-motor setups. Kits ship same day from UK and US warehouses, with most orders arriving inside 3-5 working days. The brand runs standing spend-tier discounts: £40 off when you spend £300 and £200 off past £1,000, applied on top of individual kit markdowns like £100 off the 52V 2000W MTX rim kit. It’s a practical route to an e-bike at a fraction of the price of buying one complete.
