E-Helix (Helix e-bike, Bosch SX)
Algupära
E-Helix (alates mudeliaastast 2025 ametlikult lihtsalt 'Helix') on Bergamonti esimene Bosch Performance Line SX süsteemi integreerimine — Boschi 2023. aastal turule toodud kerge keskveo mootor — ja tähistab brändi matkaplatvormi põlvkonnavahetust. Mitte-elektriline Helix on olnud Bergamonti igapäevane matkatööhobune alates 2010. aastate algusest ning uus motoriseeritud Helix võtab sama 28-tollise alumiiniumist matkaraami ja põimib 400 Wh aku alumiiniumtoru sisse, hoides jalgratta tüüpilise e-matka raskuse all. Tootevalik hõlmab kahte peamist varustustaset (Helix 10 Belt Gates CDX rihmülekandega, Helix 20 tavalise käigukangiga), millest igaüks on saadaval teemantraamis Gent või madala astmega 'Slope' raamis, mis on suunatud naisratturitele ja vanematele pendelränduritele. Valides SX mootori raskema Performance Line CX asemel, positsioneerib Bergamont Helixi kui 'esimest e-jalgratast' — piisavalt lähedal tavalise jalgratta tundele, et keegi, kes liigub tavaliselt matkajalgrattalt elektrilisele abile, ei kaotaks sõidu iseloomu.

Verdikt
- Natural, near-analogue ride feel — the lightweight Bosch Performance Line SX (~2 kg, 55 Nm) and the 21.8 kg total weight make it behave much like a normal trekking bike, ideal as a first e-bike.
- Very low maintenance on the Helix 10 Belt: Gates CDC carbon belt + Shimano Nexus 8-speed internal hub means no chain oil, no exposed cassette, quiet running.
- Fully kitted for everyday commuting/touring out of the box — integrated lights, rear rack with pannier holder, full mudguards, suspension fork and puncture-protected Schwalbe tyres.
- Inclusive sizing and frame choice: diamond and low-step 'Slope' frames share geometry, so couples or shorter/older riders can get a matched fit.
- Removable, frame-integrated Bosch CompactTube battery and a clean cockpit with the simple Purion 200 display.
- Small 400 Wh battery limits range — fine for daily commuting but short for long tours, and there is no big-battery option (range extender is an extra cost).
- 55 Nm SX motor is deliberately modest; on steep, loaded climbs it gives noticeably less punch than a Performance Line CX e-trekking bike.
- Heavy for its 'lightweight' positioning at 21.8 kg — awkward to lift up stairs or onto a rack despite the light motor.
- Component spec is mid-range value, not premium (Suntour fork, Shimano MT200 brakes, CUES/Nexus) — adequate but unexciting for the ~3,300-3,500 EUR/GBP price.
- Bergamont's confusing naming (sold simply as 'Helix' but is the e-version; multiple trims 10 Belt / 20 / Slope) makes it easy to order the wrong variant.
