The "Beryll Deluxe+ RT Gen 2 (low step-through)" model from Diamant, released in 2022, combines advanced technology with a well-thought-out design to ensure a comfortable and safe ride. Priced at 3,269 EUR, this e-bike is an attractive option for discerning cyclists. The frame is made from high-performance hydroformed aluminium tubes and features internal cable routing as well as a Motor Armor to protect the Bosch Performance Line motor with 250 watts and 65 Nm of torque. The battery, a Bosch PowerTube with a capacity of 500 Wh, is vertically integrated and, in conjunction with the Bosch Intuvia display, ensures intuitive operation.
The bike’s maximum permissible weight is 136 kg, making it robust and versatile. The hydraulic disc brakes – either Shimano MT200 or C-Star Power, each with a 180 mm brake disc – ensure reliable braking performance. The Shimano Nexus C7000 5-speed hub gear system enables precise gear changes and is combined with a coaster brake. The SR Suntour NEX fork, with 50 mm of travel and adjustable spring preload, offers additional comfort on uneven terrain.
Safety when cycling at night is ensured by the Herrmans MR GO E LED front light and the Spanninga Solo for e-bike rear light. The Schwalbe Energizer Active Plus tyres, featuring GreenGuard puncture protection and reflective strips, offer excellent grip and visibility. The ergonomically shaped handlebars and Herrmans Clik grips ensure comfortable handling, whilst the Selle Royal Nuvola saddle and the suspension aluminium seatpost provide additional comfort.
The Bontrager Connection wheelset with hollow-section rims and the Shimano TX505 hubs offer stability and durability. Practical features such as the SKS plastic mudguards, the Pletscher Comp Flex 18 kickstand and the aluminium luggage rack with MIK system round off the overall package. The Beryll Deluxe+ RT Gen 2 is therefore a well-designed e-bike that is suitable for both everyday use and longer rides.
