Razor Crazy Cart Shift Electric Go-Kart, 6+

The Razor Crazy Cart Shift is the kart that tops this guide, and it gets there on record rather than on novelty. It is listed at £250.00 — one penny more than the other Crazy Cart Shift on the page, which quotes the same 8mph top speed and the same 40 minutes of continuous use. What separates the two is not the vehicle but the paperwork: this listing shows 4.6 out of 5 from 174 ratings, while the other Shift shows 8. If the 8mph figure and the drive system that lets it spin and drift are what you want, the extra penny is not really the decision — the 174 ratings are.

Two things in this listing do not close neatly, and both are worth knowing before you buy. The product name says 'For Kids 6+', but the 'Manufacturer recommended age' field on the same page reads 6 - 8 years, so a nine-year-old sits inside the name and outside the specification table. Separately, the review count reads 174 while the five bars of the rating breakdown add up to 100 — 83 of them at five stars, and 5 at one star. Neither point is a reason to avoid the kart; both are reasons to read the listing rather than the headline. Everything on this page comes from the Amazon listing as it stands, not from a test we ran ourselves.
