Slack 63.5° head angle, 160mm travel and a long 1279mm wheelbase — composed in the chunk, confident when it gets steep, and stable through fast corners.

EMTB Forums verdict
The Pole Sonni is a Finnish-built enduro eMTB unlike anything mainstream. Its frame is CNC-machined from a solid block of 7075-T6 aerospace aluminium rather than welded or moulded, which Pole claims beats carbon on weight-to-stiffness. One platform covers a huge travel spread: an Enduro setup at 170/160mm, a Downduro at 190/200mm, and a full Downhill build at 200/200mm, so you are effectively buying a configurable gravity chassis rather than a fixed model.
Power comes from the Bosch Smart System Performance Line CX (85 Nm) fed by a sizeable 750Wh integrated PowerTube, housed in Pole's hollow-wall battery compartment. You get Pole's signature K1/K2/K3 sizing with a per-size adjust chip, plus the ability to run full 29in or mixed wheels with no adaptors and a choice of Trail or Race frame axles to tune compliance.
Complete builds lean on proven gravity kit: RockShox ZEB (or a Boxxer dual-crown on the DH), a SuperDeluxe Ultimate Air shock, SRAM GX 12-speed (GX DH on the Downhill), SRAM Code R brakes on 220/200mm rotors and Maxxis Assegai/DHR II rubber. Geometry is long and slack, with a 63.5 to 64.35 degree head angle, steep 79 to 80 degree seat angle and 448mm chainstays across all sizes.
It is consumer-direct from Jyvaskyla and priced in euros, from around 6,290 EUR for a complete Enduro and 6,490 EUR for the Downhill, or 5,565 EUR as a frameset. This is a niche, made-to-order machine for riders who want bespoke alloy engineering and bike-park-to-DH versatility, not a budget buy.

What the numbers mean on the trail
Computed from this bike's geometry, spec and build kit — reach, wheelbase, chainstay, head and seat angles, travel, motor, weight and the fork/tyre/brake spec — and worked out per size, because a fixed chainstay can make an S and an XL feel very different.

Playfulness
42
A fair bit of pop, but happiest on flowing trail rather than trials moves.
Size balance
83
Balanced front-to-rear in K2 (FC:RC 1.85) — weight sits evenly between the wheels.
Technical climbing
67
Climbs well — a 79° seat keeps the front planted. 600W of peak power and 85Nm of torque — a strong full-power motor.
Rewards commitment; it should feel calmer as the speed rises.
The numbers are well balanced for its category.
