A Floor Pump and Tubeless Setup Tool in One

The Bontrager Flash Charger Tubeless Ready 2.0 Pump is a dual-function pump that operates as both a standard floor pump for everyday tyre inflation and a dedicated tubeless tyre seating tool - without requiring a separate air compressor. The dual-chamber design is the key feature that enables both functions in a single unit: set to Inflate mode and it works exactly like a conventional floor pump for regular tyre top-ups and inflation; switch to Charge mode and it pressurises an internal chamber that can be flash-released to seat a tubeless tyre bead in one burst of air.

For riders setting up tubeless tyres at home or in the field, the traditional alternative to a flash charger pump is an air compressor - a bulky, expensive, and often unavailable piece of equipment that makes tubeless setup impractical without a workshop or garage setup. The Flash Charger 2.0 removes that barrier, making tubeless tyre setup achievable with a single pump that also handles all regular inflation tasks.

Inflation accessories are stored conveniently inside the pump handle, keeping adapters and accessories accessible without requiring a separate case or bag to carry them.

• A floor pump and a tubeless setup tool in one. Set to Charge for a pressurized chamber that makes at-home and on-the-fly setup of tubeless ready (TLR) tires a breeze.
• Dual-chamber design with Inflate setting allows for efficient use as a traditional floor pump
• Set to Charge for a pressurized chamber that inflates tubeless ready (TLR) tires without a compressor
• Digital gauge provides easy-to-read accuracy up to 160 PSI (recommended maximum)
• Compatible with both Presta and Schrader valves
• Included inflation accessories conveniently stored in handle
• Displays battery life of included CR2032 battery when powered on

Charge Mode, Presta and Schrader Compatibility, and 160 PSI Gauge

The Charge mode works by pressurising the Flash Charger's internal chamber as you pump. Once sufficient pressure is built up in the chamber, connecting to the tyre valve and releasing the stored air in a single burst delivers the concentrated airflow needed to seat a tubeless tyre bead against the rim - the critical step in tubeless setup that requires a large, fast volume of air rather than the steady flow a standard pump provides.

The pump is compatible with both Presta and Schrader valves, covering the full range of valves found across road, gravel, and mountain bike tyres. This dual-valve compatibility makes the Flash Charger 2.0 a single tool that works across a complete range of bikes rather than requiring different pumps or adapters for different valve types.

The back-lit digital gauge provides accurate pressure readings up to 160 PSI - a range that covers road tyres, gravel tyres, and mountain bike tyres from the lowest pressures used in tubeless setups to the highest pressures used in road cycling. The digital display is easier to read precisely than an analogue gauge, and the back-lit screen makes readings visible in lower-light conditions. The gauge is powered by an included CR2032 battery, and the pump displays battery life when powered on so you are not caught out by a dead gauge mid-inflation.

At-Home and On-the-Fly Tubeless Setup

The Flash Charger 2.0 is described as suitable for both at-home tubeless setup and on-the-fly use - covering the situation where a rider needs to seat a tubeless tyre during a ride after a flat or sealant failure. While it is a floor pump rather than a portable hand pump, it represents a significant reduction in setup complexity compared to needing a compressor, and for riders who transport the pump in a vehicle for longer rides or events, it provides a practical field solution for tubeless reseating that a standard floor pump cannot deliver.

For riders new to tubeless or those who have found tubeless tyre seating unreliable with a standard pump, the Flash Charger 2.0 is the purpose-built solution that makes the process consistent and repeatable without additional equipment.

FAQs

What is the difference between Inflate and Charge modes on the Flash Charger 2.0?

Inflate mode functions as a standard floor pump for regular tyre inflation. Charge mode pressurises an internal chamber - when the stored air is flash-released, it delivers the concentrated burst of air needed to seat a tubeless tyre bead without a compressor.

Can I use the Flash Charger 2.0 as a regular floor pump?

Yes. In Inflate mode the pump functions exactly like a conventional floor pump for everyday tyre top-ups and inflation.

Do I need an air compressor to set up tubeless tyres with this pump?

No. The Flash Charger 2.0 is specifically designed to replace the need for an air compressor for tubeless tyre seating. The Charge mode pressurises a chamber that delivers a flash-release burst of air sufficient to seat most tubeless tyres.

What valve types is the Flash Charger 2.0 compatible with?

The pump is compatible with both Presta and Schrader valves, covering the full range of valve types found across road, gravel, and mountain bike tyres.

What is the maximum pressure the gauge reads?

The back-lit digital gauge reads up to 160 PSI, covering the full range from low tubeless mountain bike pressures to high road tyre pressures.

What battery does the digital gauge use?

The gauge uses a CR2032 battery, which is included. The pump displays battery life when powered on.

Where are the inflation accessories stored?

The included inflation accessories are stored inside the pump handle for convenient access without a separate case or bag.
