The Sigma is built around three things that rarely appear together at this price: a forged aluminium frame, an automotive-standard Hairpin motor and a battery using Samsung 50S cells in a Greenway pack. The result is 22 kW peak and 72 Nm at 88 kg with the battery fitted – a ratio where the bike answers the throttle immediately rather than thinking about it first.
The L1E differs from the MX in exactly one thing, and it costs 5,000 PLN: road homologation. You register it, insure it and ride legally – to the trails and back, no trailer. If the machine will never leave closed ground, the MX version does the same job for less.
MX or L1E?
| Version | Who it is for | Price |
|---|---|---|
| Sigma MX | Track, closed ground, private land. No registration, no insurance. | 27,900 PLN |
| Sigma L1E | Riding to the trails on public roads, daily use, legal traffic. | 32,900 PLN |
| The difference | Same machine, same performance. You pay purely for homologation and the ability to register it. | 5,000 PLN |
L1e is the EU moped category: registration, plate, insurance and an AM or B licence. The manufacturer does not publish a top speed for the road version in its table – we do not publish a number we do not have. Ask us for the figure on the specific unit.

Before you compare with a cheaper offer
A forged aluminium frame, not a cast one. An automotive-standard Hairpin motor, not an industrial unit. Samsung 50S cells in a Greenway pack, not unnamed "grade A cells". Those three items account for most of the price difference and for what you will feel after a year of use.

- If the bike will only be ridden on closed ground, the MX version costs 5,000 PLN less.
Frequently asked
What is the difference between L1E and MX?
Road homologation, nothing else. Motor, battery, frame, suspension and wheels are identical. The L1E can be registered and ridden legally on public roads; the MX cannot.
What is the real range?
The manufacturer does not publish range with measurement conditions, so we do not quote a number. The reference points we do have: a 3.402 kWh battery on an 88 kg machine. Range depends on ride mode, terrain and rider weight far more than on any catalogue figure.
Will I get service in Poland?
Yes. We are an authorised Altis Powersports dealer – warranty, service and spare parts are handled in Poland, with no need to ship the bike abroad.
