This early Amazon Prime Day deal drops the Hammerhead Karoo bike computer by $85

Amazon’s early Prime Day discounts have already delivered a standout deal for cyclists, with the Hammerhead Karoo 3 bike computer now available for $440—a reduction of $85 from its standard $529 price. The Karoo 3, praised for its navigation precision and 4.5-star rating in Cyclingnews’ review, competes closely with top-tier models like Garmin’s Edge 1050, though at a significantly lower cost.

Its multi-band GNSS technology ensures reliable tracking across varied terrain, while features like touchscreen mapping and seamless route creation from Google or Apple Maps add practical value for riders. UK shoppers can secure an even deeper discount, with Sigma Sports offering the Karoo 3 for £359—nearly £100 off its usual £450 price—alongside free delivery on orders over £50.

The sale runs for 48 hours starting October 6th, though Prime membership is required to access Amazon’s deals, with a free 30-day trial available before the $14.99 monthly fee applies.
