City bike pump and puncture repair

What pump for a city bike?

For daily rides, two pumps work well together: one stays at home, the other travels with you.

• Floor pump: kept in the hallway or bike room, it inflates in a few strokes and its pressure gauge shows the actual pressure. It’s it that prevents you from riding under-inflated.
• Mini pump: it fits in a bag or attaches to the frame, often on the bottle holder mounts. The shorter it is, the more strokes are needed to fill a wide tyre.
• Frame pump: the classic pump for city bikes, secured between two points of the frame, like the Zefal Tradi 810.
• Electric inflator: rechargeable and compact, it fills the tyre effortlessly, handy when you're in work clothes.

CO2 cartridges, quick but for single use, are mostly used for sports outings; in the city, a mini pump is enough and never runs out.

Schrader, Presta or Dunlop: identifying your bike's valve

Check the valve before choosing the pump. Wide and fitted with a small central button, the Schrader valve equips many city bikes and e-bikes; it also accepts the inflator from a petrol station. Thin and ending with a screw-on nut, the Presta valve is found on sporty urban bikes and road bikes converted to city use. Some city bikes have a Dunlop valve: check that the pump head accepts it, like the Multivalve head of the SKS Rennkompressor, designed for Dunlop, Presta and Schrader valves. If your pump only has a Schrader connection, a small adapter screwed onto a Presta valve, like the Zefal transformer, allows you to inflate it.

Wide tyres and moderate pressure: inflate just right in the city

A city tyre contains a lot of air at a relatively low pressure, marked in bar or PSI on its sidewall. High volume pumps, marked HV, are more effective for this than high-pressure models, marked HP, which are made for thin tyres. Kheax offers its mini pump Lips in both HV version, limited to 6.2 bars, and HP version, up to 9.7 bars; the floor pump Kellys Switchflow switches between modes. An under-inflated tyre wears out faster and risks pinching the tube against the rim when going over a curb: check the pressure regularly, as a tyre loses air even without a puncture.

Puncture in the city: prevent and repair

Broken glass, staples and gravel make punctures frequent in the city. The first prevention is a well-inflated tyre, then a puncture-resistant tyre, to be chosen from the urban wheels and tyres. On a tubeless tyre, a preventive liquid seals small punctures while riding. To repair on the go, keep in your bag a mini pump compatible with your valve, tyre levers and a spare tube or patches. On an e-bike with a motor in the rear wheel, removing the wheel takes more time: it’s often easier to take the tube out from one side of the tyre without removing the wheel to apply a patch.

Pumps and repair for other bikes

For a road bike, the road pumps and repair section includes high-pressure models and CO2 regulator heads; for off-road, the MTB pumps and repair add shock pump options. All parts for the routine maintenance of your city bike, including brakes, saddles, and pedals, can be found in the urban wheels and components.

Which pump brands for the city?

Zefal covers all useful formats in the city: Tradi 810 pump to fit between two points on the frame, aluminium Z-Twin floor pump comes with a carrying bag, and transformers that adapt a Presta valve to a Schrader fitting.

SKS offers the EMP electric inflator, 151 g for up to 8.3 bars, the Airstep 7.0 floor pump, limited to 7 bars and fitted with a Multivalve head, and the Rennkompressor in the Multivalve version for Dunlop valves.

Kheax, a French bike accessory brand, builds its Atlas floor pump around a steel body and a wooden handle, with a reversible Presta and Schrader connection and a 75 mm gauge.

Kellys equips its Switchflow floor pump with a double head for all types of valves and a selector between high volume and high-pressure inflation, and completes its range of mini pumps with Doubly Pro and preventive liquid Milkyseal.

Frequently asked questions

How to repair a city bike puncture?

Identify the cause by running your fingers inside the tyre to remove the shard or thorn. Take out the tube, locate the hole by inflating it slightly, apply a patch on a sanded and clean surface, and then reinstall the tube making sure not to pinch it with the levers. Inflate to the pressure indicated on the sidewall.

Can you inflate a bike tyre at a petrol station?

Yes, if the valve is of the Schrader type, or with an adapter on a Presta valve. Go slowly with short bursts: the compressor fills a bike tyre in seconds and can exceed the tyre's maximum pressure. Check the displayed value before you leave.

How often should you inflate a city bike tyre?

A tyre naturally loses air, even without a puncture. A check every two weeks or so with the floor pump's gauge keeps it at the right pressure; if the tyre deflates within a few days, look for a small puncture or a leaking valve.

Is an electric pump useful in the city?

It saves effort and fits in a bag: the SKS EMP weighs 151 g and inflates up to 8.3 bars, which is enough for a city tyre. Remember to recharge it, and keep a floor pump at home for regular checks.

What pump for an electric city bike?

A high volume floor pump with a gauge, with a head that fits the bike's valve, often Schrader. The tyres on an electric bike, wide and carrying more weight, do not handle under-inflation well: respect the pressure range indicated on their sidewalls.
