The Sixthreezero site is running an Up to 50% Off All Bikes sale, and that 50% off event is the main deal to use if you plan to buy a bike. The discount is applied automatically at checkout, so it is best for shoppers who want a new Sixthreezero bike and want the largest single saving on full price or sale models.
If you are buying a bike: the Up to 50% Off All Bikes sale applies. For a $1,200 bike, for example, the site takes 50% off at checkout, leaving a final price of $600 and a saving of $600. The discount is automatic so you do not need a promo code.
If you want fenders only: choose the Fenders Under $79.99 deals. Prices are as marked; on a $79.99 fender you pay $79.99. This is the simplest option for small purchases where the bike sale does not change component prices.
If you need batteries or chargers: the Batteries & Chargers From $39.99 deals are the best fit. With starters at $39.99 you pay the marked price; for a $39.99 charger you pay $39.99, which is the lowest threshold shown and will beat applying a bike discount that only applies to bikes.
Buying accessories plus a bike: the bike sale is automatic and applies to bikes only, while fenders and batteries are shown at marked prices. If your cart mixes a bike with accessories, the 50% off applies to the bike portion only, so calculate the bike saving separately and add the marked accessory totals. The offer terms do not state that additional codes combine with the sale, so treat the sale as the priced reduction on bikes and accessories as their marked prices.
Our records show eight sales and deals for Sixthreezero in the 12 months to October 2026, and the biggest percentage sale in that window was up to 50% off, which matches the current biggest deal. Our records show no team checkout checks for this brand in the 12 months to October 2026.
Choose the option that leaves the lower total for your cart: if you are buying any bike, the Up to 50% Off All Bikes sale will usually give the biggest saving because it halves a bike price at checkout. If you are buying only accessories, take the marked Fenders Under $79.99 or Batteries & Chargers From $39.99 offers, since the bike discount does not reduce accessory list prices.
