A Nairobi battery-as-a-service operator with two very different machines (the workhorse Bidii Boda and the budget Corbett) and a funded, solar-backed swap network built for African grid realities. The numbers decoded, the swap economics, and which bike you actually mean. Sources on everything.
First, know which bike you mean. The headline specs here are the Bidii Boda: ~5.1 kW, a claimed ~85 km (53 mi) range, and a ~90 km/h (56 mph) top speed on two 1.44 kWh LFP packs. The cheaper Corbett is slower (~1.2 kW, ~60 km, ~60 km/h, one pack). Both run on Arc Ride's solar-backed swap stations: swap in under a couple of minutes, from KES 350/day unlimited or KES 185/swap. A funded network, not a pilot.
Arc Ride rents packs and runs the stations: riders pay from KES 350/day for unlimited swaps or KES 185 per swap, and never own a battery. A full 5-year, dollar-denominated cost-to-own for this model is still being itemized: we will not convert currencies, model the daily-plan economics, or invent a resale figure for a commercial fleet. The verifiable swap pricing and the per-kilometre energy math are in §9.
Every module behind the headlines: who it is for, the two bikes, claims vs. physics, the solar-backed network, what it costs, and the standard scorecard. All sourced, with gaps marked honestly.
Arc Ride is a Nairobi battery-as-a-service operator building swap infrastructure for electric two- and three-wheelers across Africa. It runs two honestly different bikes: the Bidii Boda workhorse (~5.1 kW, ~85 km, ~90 km/h, two 1.44 kWh LFP packs) and the budget Corbett (~1.2 kW, ~60 km, ~60 km/h, one pack). Its stations swap packs in under a couple of minutes and stay running through grid outages on 405 W solar plus the packs themselves. It raised about $10 million in late 2025 to expand. Just be clear which bike you mean before comparing numbers.
Start here, and the first question is which of the two bikes you are actually looking at.
Two bikes, two answers, plus the network constraint every swap operator shares. Pick the bike to the job, and check coverage.
The workhorse. ~5.1 kW, ~85 km of range, and ~90 km/h give a real earning day's pace and range, with swaps to extend it. The right pick if you need to keep moving and making money.
Cheaper and slower: ~1.2 kW, ~60 km, ~60 km/h on one pack. Sensible if budget and short urban routes matter more than pace, but know you are buying the slower bike.
Commercial users have included delivery operators relying on the swap system, a useful real-world signal that the network has to actually work. The solar backup helps uptime through outages.
As with every swap operator, the value lives and dies with station coverage. No stations on your routes means no charged packs. Verify the network reaches you first.
The single most important thing here is not claim-versus-real, it is Bidii-versus-Corbett. Conflating the two is the easiest way to be misled.
What is genuinely clever, and which "innovations" are table-stakes. Arc Ride's real edge is in the stations.
The network is the product, and one feature genuinely stands out. Each badge tells you whether it is a real edge, normal for the segment, or marketing gloss.
The automated stations swap packs in under two minutes and stay running through grid outages on 405 W solar PV plus the batteries themselves as backup. In a market where the power is not always on, a swap network that survives a blackout is worth more than one that does not. This is the genuine edge.
★ Genuine edgeThis is not a pilot. Arc Ride raised about $10 million in late 2025 to expand the battery-exchange network, working with partners on energy infrastructure. Scale and funding are themselves a meaningful reliability signal for a service business.
★ Genuine edgeArc Ride rents packs rather than selling them, removing the rider's single most expensive, most failure-prone component from their balance sheet. Standard for the model, but a real ownership advantage.
✓ SolidThe Bidii Boda for pace and range, the Corbett for budget. A clear good-better split so a rider can match the machine to the route, as long as they know which one they are buying.
✓ SolidSelf-service cabinets that exchange a pack in under a couple of minutes. Genuinely convenient, but automated swap cabinets are becoming the baseline expectation across African operators.
≈ Now standardMarketing claims vs. the physics. Arc Ride publishes more than most, so we can actually run some of the math here.
Arc Ride publishes a motor power for the Bidii Boda, so we can convert it to the unit a rider feels. As always, ask whether a wattage is continuous or peak.
Here Arc Ride gives us a real anchor: the pack is a 1.44 kWh LFP, with the Bidii running two and the Corbett one. So we can actually do the energy math.
Step 1, the energy. The Bidii carries two 1.44 kWh LFP packs, so its nominal energy is roughly:
Step 2, the implied consumption. Divide usable energy by the claimed range to see what consumption the marketing assumed.
The standard charge-time formula does not describe this bike's real refuel, because the rider swaps rather than charges. Arc Ride adds a genuinely smart resilience layer.
Priced for the Kenyan commercial market as a daily plan or per-swap fee. We show what is sourced and flag the rest as not yet itemized.
A full 5-year, dollar cost-to-own is still being itemized, because daily-plan economics, currency, and the local resale market are not things we will model from guesses. Here is what is sourced.
| Line item | Reported | Notes |
|---|---|---|
| Energy (unlimited) | from KES 350 / day | Unlimited swaps; ~$2.54/day at the reported rate |
| Energy (per swap) | KES 185 / swap | Standard single swap; ~$1.34 |
| Battery | leased, not bought | Arc Ride retains and manages the LFP packs |
| Hardware | Bidii or Corbett | Purchase / financing terms not itemized here |
| Full 5-year US-style cost-to-own | being itemized | We never guess plan or currency figures |
Why electric wins on energy in Kenya. Independent of Arc Ride's own pricing, the local arithmetic favours electric for a boda. Kenya petrol runs near KES 178 per litre while grid electricity is roughly KES 25 per kWh, and studies put electric boda energy at about 1 to 2 KES per kilometre versus roughly 6 to 8 KES per kilometre on petrol.
What the model depends on, who supports it, and what we genuinely do not yet know.
There is not yet a large, independent owner-reliability record to summarise. We will not invent owner quotes or themes. Here is what can be said responsibly, including a couple of genuine positive signals.
For a swap-network bike, "parts" is two questions: ordinary spares, and swap-station density. The second matters more, and here the funding helps.
Arc Ride has been rolling out stations at scale across Nairobi and raised about $10 million in late 2025 specifically to expand the network, which is the most important "part" of the whole proposition. For ordinary consumables, treat availability as operator-dependent and confirm locally. We do not have a verified current station count to publish, so check coverage on your routes before committing.
| What you depend on | Status | Confirm |
|---|---|---|
| Swap-station coverage on your routes | verify locally | the decisive factor |
| Network expansion | funded ($10M, 2025) | via Arc Ride |
| Battery (leased LFP, not owned) | network handles it | swapped, not bought |
| Ordinary consumables (tyres, brakes) | operator-dependent | ask Arc Ride |
One scorecard, identical axes on every bike.
Every e-moto on the site is scored on these same eight axes, by the same rules. We score the Bidii Boda here; the Corbett would rate lower on range and power. Thin bike-level reliability data holds some scores toward the middle.
Our standing methodology, run identically on every e-moto, including bikes where the maker has not published every input.
The only honest way to compare two batteries. Arc Ride publishes pack kWh (1.44 kWh LFP), so we use that; the V/Ah split is not published.
You never use 0 to 100%. The BMS holds a reserve and voltage tapers at the bottom. We assume ~88%.
Consumption is the lever. The Bidii's ~85 km implies ~30 Wh/km; loaded or faster, expect more. Drag rises with speed².
Always ask which number a spec quotes. 5.1 kW gives ~7 hp (Bidii); 1.2 kW gives ~1.6 hp (Corbett); continuous vs peak is unstated.
For a swap bike this is academic: the rider exchanges packs rather than charging, so swap time is the real metric.
| Cost assumption | We used | Change it if… |
|---|---|---|
| Energy basis | Local KES per swap / day, not US kWh | Arc Ride's plan pricing differs |
| Electricity rate | ~KES 25 / kWh (Kenya grid) | Tariff tiers and levies vary |
| Petrol benchmark | ~KES 178 / litre (2026) | EPRA reviews move it |
| Battery | Leased LFP, not owned | BaaS plan terms apply |
| Resale | Not modelled (commercial fleet) | Local market differs from US |
