Beto Double Shot Mini Pump
This double action mini pump from Beto works by pumping air into your tyres on both the pull and push of the handle. It also has a manometer (pressure gauge)to tell you exactly how much pressure is in your tyres with easy to read markings to. With fittings for both Schrader and Presta valves, you can attach this onto almost any inner tube and it has a locking head to stop it from detaching from the valve while you are pumping. The bracket screws onto the bottle cage are and you can easily clip the pump onto it to store it away or just keep it in your saddlebag. Made of aluminium alloy, it weighs 200 grammes and features a dust protection cap, stopping dirt from getting into the mechanism.
Under inflated tyres increase the rolling resistance of the bike and will reduce the range which you get from your electric bike.
