Pressure monitoring for two- and three-wheelers in Kenya The working two-wheeler is a boda boda, the working three-wheeler is a tuk-tuk, and both are bought to earn. What decides the sale is the fitted cost, not the data sheet.
Talk about a programme See the sensorWhat the market actually looks like
In Kenya the two- and three-wheeler is transport that pays for itself. A boda boda carries a passenger across town, a tuk-tuk carries three or four of them, and the vehicle is expected to work every day it is able to. That single fact decides what a pressure sensor has to be: cheap enough to add to a vehicle that already costs its owner money every morning, and simple enough to fit in a roadside workshop.
Much of the fleet is not bought new. Imported used motorcycles and three-wheelers are repaired, rebuilt and kept running well past the age at which a European owner would have replaced them. Tyres are patched rather than replaced, tubes are fitted more than once, and the valve may be whatever the last workshop had in the drawer. A sensor that screws onto the valve has an advantage here, because it does not care whether the wheel is original and it does not need a mounting point that a used vehicle never had.
The channel is layered. An importer or wholesaler in Nairobi or Mombasa brings stock in, a regional distributor moves it out, and the last step is a spare-parts shop or a tyre fitter who sells to the rider. Each layer wants a different pack, and the part that survives is the one a small shop can stock beside tubes and brake shoes without tying up cash. That is why the receiver matters as a commercial question and not only as an engineering one: it is another part to buy, another part to mount, and another step somebody has to be paid to perform.
What fits this market
- One SKU across makes. The sensor fits the valve, not the vehicle, so a distributor is not asked to stock a part number per brand or per model year.
- No receiver, no harness, no display. Three items leave the bill of materials and three steps leave the fitting time.
- Workshop-level fitting. Screw it on, pair it with a phone, done — no specialist tool and no second visit to configure it.
- A cell a shop can stock. The CR1632 is replaceable and lasts about 1.5 years on average, so it is a service item rather than a sealed unit that gets thrown away with the sensor.
- Positions marked at the factory. Front and rear, so a reading never has to be guessed at by whoever fits it.
What we can do for a programme here
- English labelling, with artwork agreed for your market rather than fixed by us.
- Your brand on the sensor, the pack and the app.
- Cartons for a wholesaler and small retail packs for a roadside shop — this channel usually wants both from the same supplier.
- Marking conventions agreed with you, including the wording the workshop will actually read.
- A first order sized to test one town or one region instead of a national launch.
- Answers in writing, because a verbal assurance is worth nothing once the container is on the water.
Heat, murram and a loaded bike: what the tyre actually sees
Ambient temperature is high for most of the year, and a tyre that stands in the sun and then runs on hot tarmac gains pressure as it warms. That is ordinary physics, and it is why the useful reading is the one taken cold, before the day's work — which is exactly the reading nobody takes. Our app shows pressure and temperature per wheel, so a rise that is only heat can be told apart from a wheel that is genuinely losing air.
The dry season brings dust, and dust works its way into valve cores and around beads. The wet season brings standing water and potholes that were not there the week before. Outside the cities the surface is often murram, a gravel road that is graded now and rutted later; an impact that damages a bead or bends a rim can start a slow leak which only becomes visible later, usually as a ruined casing. In both seasons the failure is gradual, and gradual failures are the ones a daily check catches.
Then there is load. A boda boda carries a passenger and often a delivery on the same trip as well, and a tuk-tuk is loaded beyond the figure in the manual as a matter of routine. A soft tyre under that load does not feel like a slow leak to the rider; it feels like the vehicle wandering under braking, and it is paid for in fuel every kilometre. Second-hand tyres and patched tubes are part of the same picture: a patch that weeps and a tube that has been fitted twice are exactly the failures a trend catches and a single gauge reading hides.
What the sensor is, in full
| Wireless | Bluetooth 5.1, 2.4 GHz — no receiver required; the phone is the reader |
|---|---|
| Pressure range | 0–500 kPa gauge (0–600 kPa absolute), about 5 bar |
| Accuracy | ±2 kPa |
| Battery | Replaceable CR1632, average service life about 1.5 years; no re-pairing after a change |
| Operating temperature | −20…+80 °C |
| Sealing | IP67 |
| Size | Ø21 × 16 mm |
A receiver can be built to order when the data has to reach a controller or a display instead of a phone — serial (UART) or CAN output. That is a different configuration, not a different sensor. Specifications are subject to change; laser marking follows the wheel positions and branding agreed for your programme.
What we do not do
- We do not quote market-size figures. Volumes differ by county, by town and by channel, and a number from a report would not describe the street your distributor actually sells on. Ask your own distributor — they know.
- We do not assume a regulatory position for you. Requirements differ by product, channel and destination; ask us and we answer with the current status for your market, in writing, rather than with a generic statement.
- We do not name our customers. If you want a reference, tell us which market and which channel, and we will say what we can say.
Tell us three things and we can answer properly
Which matters far more than a long enquiry: the vehicle class (boda boda, passenger tuk-tuk, cargo three-wheeler), the number of wheels on each vehicle, and the market you are selling into. With those three we can say which configuration fits, what the labelling should say, and whether the standard pressure range covers the tyres you actually run. The same reasoning is written up for Nigeria and the Philippines, and the full list sits on the markets index.
