Helix Women's

city3199–3799 GBP

Origin

2025. The Helix name returned after a 5-year absence as a fully different product — an e-urban bike rather than an acoustic hardtail. Bergamont chose the Helix name deliberately to connect with existing brand loyalists while signalling a new direction. The Slope (trapezoid) frame variant is targeted explicitly at women wanting urban e-mobility with sporty character. The Bosch Performance Line SX was chosen over the heavier CX to keep the bike light and agile for city use.

The verdict

+Strengths

Bosch Performance Line SX (55Nm, 2.1kg) — lightest full Bosch motor. Bike feels more natural and less 'electric'.
CompactTube 400Wh IS removable — indoor charging in apartment possible. Key Baltic advantage.
PowerMore range extender compatible — 400+250Wh total for longer days
SR Suntour NRX32 AIR fork at 75mm — adjustable for rider weight, better than coil at this price
Schwalbe G-One Overland 365 50mm — all-season, all-surface, puncture protected. Year-round Baltic use capable.
Full equipment standard: lights, rack, fenders, kickstand — no extras needed
Slope frame genuinely easier step-through — lower standover than diamond, easier for shorter riders or skirts/dresses
Belt + hub gear option (10 Belt) — zero maintenance drivetrain on an e-bike. Rare combination.
Shimano CUES Linkglide — new unified trekking groupset, reinforced for e-bike chain loads
Colour-codes spec — unusual but transparent once understood

−Weaknesses

400Wh is smaller than typical e-trekking competitors (Bosch PowerTube 625Wh standard on Horizon) — shorter range
55Nm (SX) less punch than 85Nm (CX) on steep climbs under load
SR Suntour — consistent Bergamont weakness. NRX32 air is better than coil but not RockShox/Fox quality.
Only 3 sizes (SM/MD/LG) — narrower fit range than Horizon or Vitess
PowerMore on Slope top tube is an awkward position aesthetically — compromises clean look
New model (2025) — limited long-term reliability data
Limited English-language press coverage of 2025 Helix at time of writing

Did you know

01The Helix 10 Belt Slope is the first Bergamont e-bike to combine Bosch SX motor with Gates belt drive + hub gear — a triple innovation: lightest Bosch motor + zero-maintenance drivetrain + step-through frame, all in one product.
02Colour coding = spec coding: each of the 4 Helix colours indicates a specific equipment variant. Buy the right colour to get the right spec — unusual and potentially confusing, but Bergamont commits to it.
03The PowerMore range extender mounts on the TOP TUBE on Slope frames — because the trapezoid frame has no standard downtube mounting position. Bergamont specifically engineered this placement for the women's frame.
04The original Helix (2016–2020) was never an e-bike — it was a flat-bar hardtail hybrid. The 2025 Helix shares nothing technically with its predecessor except the name and the downtube/chainstay graphic ornaments.
05SR Suntour NRX32 is an AIR fork at this price point — not coil spring. Air forks are adjustable for rider weight and give more consistent performance across conditions.
06Schwalbe G-One Overland 365 tyres at 50mm — 'all-season' compound (365 = 365 days). Designed for year-round use in mixed conditions, including light gravel.
07The Helix is positioned as 'first e-bike' product — ebike24 describes it as 'aimed at those who want to experience for the first time how much easier a motor and a battery can make cycling'.
