The Brennabor A-88e Diamant, launched in 2023, is a high-quality e-bike priced at EUR 4,399, positioning it in the upper mid-range. It features a robust Bosch Intube frame made from 6061 aluminium in a diamond shape, with a frame size of 52 cm. The maximum permissible weight is 140 kg, whilst the bike itself weighs 28 kg.
The braking system consists of SHIMANO ‘BR-MT420/420’ brakes, which include high-performance disc brakes at both the front and rear, with a diameter of 203 mm at the front and 180 mm at the rear. The drivetrain is a 1x11-speed SHIMANO “XT Linkglide”, which ensures precise and reliable gear changes. The fork is a ROCK SHOX “Recon Silver RL” with an adjustable lockout and 100 mm of travel, ensuring a comfortable ride across a variety of terrains.
Lighting is provided by a CONTEC “Dlux 80 E+” front light with 80 lux and a CONTEC “CTL-335 E-Stop” rear light, which features an integrated brake light. Power is provided by a BOSCH Gen.4 “Performance CX” mid-drive motor with an output of 250 W and a BOSCH “Powertube 625” battery with a capacity of 625 Wh. The battery is charged using a BOSCH 4 Ah charger, and the BOSCH “Kiox 300” display offers intuitive control with four assistance levels and a push-assist function.
The bike is fitted with CONTINENTAL “Ruban Plus” tyres, which are mounted on hollow-section rims and provide additional safety thanks to their reflective strips. The ERGOTEC “Low Riser” handlebars and the adjustable ERGOTEC “Sephia Ahead” stem provide a comfortable riding position. The SELLE ROYAL “Essenza Plus” saddle, combined with the LIMOTEC “B3” seatpost – which offers both suspension and a dropper function – contributes to a comfortable ride.
Additional features such as SKS mudguards, an adjustable URSUS “King2” kickstand, and a MASSLOAD “CL648” luggage rack with MIK system make the A-88e Diamant a versatile and practical companion for everyday use and on tours. The combination of high-quality components and well-thought-out design makes this model an attractive choice for discerning e-bike riders.
