CYCLAMI A2S vs CYCPLUS AS2 Pro and Pro Max: UK Guide

Compare the CYCLAMI A2S with the separate CYCPLUS AS2 Pro and Pro Max by weight, pressure, tyre task, heat, portability and backup needs.

rite-refresh-marker: CYCLAMI-PILOT-20260815-COMPARISON

The CYCLAMI A2S, CYCPLUS AS2 Pro and CYCPLUS AS2 Pro Max are products from two different brands. That identity point comes first because similar model names can make an online comparison look like one manufacturer’s range when it is not. CYCLAMI makes the A2S discussed on this site; CYCPLUS makes the AS2 Pro and AS2 Pro Max.

All three are compact rechargeable tyre inflators, but a shared 120 PSI headline does not make them equivalent. A rider topping up a 28 mm road tyre has a different air-volume and heat task from someone recovering a large gravel, mountain-bike or motorcycle tyre. This guide compares published specifications and intended use. It is not a hands-on test and does not infer performance that either manufacturer has not published.

The short answer

• Consider the CYCLAMI A2S when you want a compact, pressure-controlled pump sold with clear CYCLAMI specifications and a UK purchase route. The manufacturer lists it at about 136 g, with 120 PSI maximum pressure, 18 L/min airflow and USB-C charging. The UK retail page captured on 15 August 2026 additionally displayed a 45-minute charge time.
• Consider the CYCPLUS AS2 Pro when CYCPLUS’s 120 g format, built-in pressure reading and stated everyday/emergency positioning better match your priorities.
• Consider the CYCPLUS AS2 Pro Max when larger-volume tasks matter more than minimum carry weight. CYCPLUS lists it at 205 g and describes it as the higher-volume option for uses including mountain bikes and motorcycles.

Whichever one you choose, keep a manual pump on remote rides. Batteries discharge, small pumps become hot, adapters can be lost and a published maximum pressure says nothing about how many demanding inflations a particular trip may require.

Published specification comparison

Model	Brand	Published weight	Published maximum	Positioning supported by source
A2S	CYCLAMI	136 g	120 PSI	Compact rechargeable inflator with preset pressure and auto-stop
AS2 Pro	CYCPLUS	120 g	120 PSI	Pressure display and everyday/emergency use
AS2 Pro Max	CYCPLUS	205 g	120 PSI	Higher-volume use, including MTB and motorcycle tyres

CYCLAMI’s manufacturer page also lists the A2S at 73.6 x 45 x 28.6 mm, with 2 x 500 mAh battery capacity, 18 L/min airflow and USB-C charging. The current CYCLAMI A2S retail page, captured on 15 August 2026, additionally displayed 7.4 V and a 45-minute charge time. Recheck those fields, price, package contents and availability before purchase.

CYCPLUS’s range page lists 120 g for the AS2 Pro and 205 g for the AS2 Pro Max. Its AS2 Pro page also describes real-time pressure display, preset auto-stop and a 30-minute charge. Those are CYCPLUS claims about its product, not CYCLAMI A2S specifications.

Why 120 PSI does not settle the decision

Maximum pressure is a ceiling, not a complete workload description. The pump must move a volume of air while controlling heat and drawing energy from a small battery. Two tyres can both need less than 120 PSI yet present very different jobs.

A narrow road tyre brought from a partly inflated state to riding pressure needs much less air than a large-volume tyre starting near empty. A quick pre-ride top-up is also easier than reinflating after a tube change. Compare products against four details you can write down:

1. tyre width and wheel size;
2. realistic starting pressure after the failure you expect;
3. target pressure within tyre and rim limits;
4. number of tyres you may need to inflate before recharging.

If a seller gives only maximum PSI, do not translate it into an assumed inflation count. Ask for a test condition that matches your tyre, or plan around the uncertainty.

Road, gravel and higher-volume use

For a road rider, low carry weight and pressure control may dominate. A compact pump can remove much of the repetitive effort of a manual mini pump, especially when a repaired tube needs a measured final pressure. Check that the nozzle or hose works with your valve and rim depth before relying on it outdoors.

For gravel, tyre volume rises and preferred pressure is often lower. That shifts the question from maximum PSI towards airflow, battery endurance and heat. CYCLAMI publishes 18 L/min for the A2S, but that number still does not predict every gravel setup. Tyre casing, remaining pressure, temperature, valve access and pauses all affect the real task.

For mountain-bike or motorcycle use, CYCPLUS explicitly positions the Pro Max as its more robust, higher-volume model. That makes it the more relevant CYCPLUS comparison than simply picking the lightest device. It does not remove the need to check the exact tyre specification or to carry equipment appropriate to the vehicle.

Our portable electric pump buying guide explains the pressure, volume and fallback checks in more detail.

Heat, valves and safe handling

Small electric inflators can become hot around the outlet and connector. Use the protective parts supplied for the exact model, follow its duty-cycle and cooling instructions, and avoid touching hot metal immediately after inflation. Stop if the device, hose, valve or battery behaves abnormally.

Confirm whether your bike has Presta or Schrader valves, whether an adapter is required and whether a deep rim leaves enough valve exposed. An extension hose can reduce strain on a valve, but only if it is approved for the pump and seals correctly. Do not force a mismatched head onto a valve or treat an adapter as interchangeable merely because the thread starts to engage.

Battery and charging questions

The CYCLAMI manufacturer specification states 2 x 500 mAh battery capacity and USB-C charging. The dated cyclami.co.uk retail-page capture additionally displayed 7.4 V and a 45-minute charge. CYCPLUS publishes different charging and endurance information for its own products. Battery capacity figures are not directly useful unless voltage, control electronics, motor load and the test tyre are also considered.

For any model:

• charge it according to the manufacturer before the ride;
• check it periodically rather than leaving it untouched for months;
• protect it from impact, contamination and unintended activation;
• do not charge a damaged, swollen or unusually hot device;
• verify baggage rules with the airline before flying.

For an unsupported route or multi-day ride, the best redundancy is still a small manual pump. Our bikepacking pump guide covers this failure planning.

Cost is more than the purchase price

Compare the delivered UK price, included hose and adapters, warranty provider, returns route and replacement-part availability. A lighter pump that requires a separately purchased hose may not be the lighter or cheaper complete system. A higher-priced model may be rational if it better fits a known tyre task, but a larger specification is not automatically better for a rider who needs one emergency road top-up.

Rechargeable pumps also compete with CO2 and manual pumps. Electricity, cartridges, adapters and replacement equipment all have costs. Use the worked method in our electric pump versus CO2 guide instead of assuming that one category is always cheapest.

Final choice checklist

Choose only after you can answer these questions:

• Is the listing for CYCLAMI or CYCPLUS, and does the supplied model exactly match it?
• Does the evidence describe your tyre size, starting pressure and target pressure?
• Are the valve connection and deep-rim access suitable?
• What cooling pauses and protective parts does the manual require?
• Can the seller support warranty and returns in the UK?
• What is your fallback if the battery, connector or device fails?

The CYCLAMI A2S is not an AS2 Pro or Pro Max. The CYCPLUS models are not CYCLAMI variants. Keeping that distinction clear turns a confusing name comparison into a practical choice about tyre workload, carry weight and redundancy.
