BH iLynx Race 7.8 EC785 2024 Showroom

What immediately catches my eye as a visually sensitive person is the clean aesthetics of the iLynx Race.
This is mainly due to the beautifully integrated 630 Wh battery and the compact motor. The discreet control via the iRemote and the cables and lines routed through the stem contribute to this as well.

The seat clamp integrated into the top tube is the logical consequence of this design language. The side profile of modern mountain bikes, whether with or without a motor, is increasingly drifting, at least in terms of cables and lines, towards a road bike cockpit.
The massive axle at the main pivot point of the bearing is said to provide 30% more torsional stiffness compared to the previous model - and this despite the competitive frame weight of 2,065 g including the shock absorber.

HCIM (Hollow Core Internal Molding) is the manufacturing process used to produce BH's high-end frames. This process transforms a super-lightweight stack of precisely cut and carefully laid high-modulus carbon fibers and mats into a mountain bike frame that withstands powerful roots on descents and delivers solid watts on climbs.
The frame geometry, as befits a marathon bike, is not overly downhill-oriented and, with a 68° head angle and 430 mm chainstay length, would more likely be counted among the agile bikes in the twisty forest trails.

Tech Specs

The design on the handlebar is quite impressive. The iRemote is a great feature with its minimalist 4-LED display, a plus and minus button, and a power button. What more do you need? Especially when, as only a few motor manufacturers do, the system is kept open for a Garmin connection. This allows the Garmin to be ideally used as a display for the riding modes and other system statuses.
With the BH iConnect app, motor characteristics and support levels can be adjusted.

SEG Automotive specializes as an automotive supplier in high-quality, reliable components across all areas of mobility, from car windshield wiper motors to larger hybrid drives and small generators. Accordingly, the partnership plans between BH and SEG were ambitious.
With a motor weight of 2.1 kg and a torque of 65 Nm at a continuous output of 250 W and a peak power of 500 W, the SEG motor is definitely among the most competitive in its class in terms of power-to-weight ratio.

A special feature of the BHZ is the control system, which monitors torque, speed, and cadence at a frequency of 1000 measurements per second and optimizes motor regulation accordingly - from the smooth fade-in and fade-out at the 25 km/h speed limit to the motor pre-tensioning on inclines. The latter is intended to significantly ease starting on climbs.
A nice and not insignificant detail is the 5-year warranty that BH provides on the motor.

630 watt-hours at 2.6 kg battery weight is a decent size for a lightweight e-bike drive unit. Such a motor-battery combo would have cost us significantly fewer reserves during our autumnal gravel tour from Loisium to Loisium than the 360 Wh from the Trek Domane+.
All BH iLynx Race and Trail models feature the new battery, which is built from 21700 cells with 5.8 Ah. They form the basis.

Geometry

The optional XPro DD battery with 180 Wh increases the range according to BH to up to 4,600 meters of elevation gain, although I claim that a David Valero will also crack the 5,000 meters of elevation gain with it. In any case, the BH specification in "Elevation Gain" makes more sense than any kilometer indications.
Either way, 810 Wh is a lot and is usually sufficient for day-tour-worthy horizontal and vertical ranges with a system weight of under 100 kg and corresponding bio-watts from your own legs.
