Description
Versatile e-bike with a rear-hub motor and AVS racks front and rear
The Humber Flex is a modern, versatile e-bike designed to handle both everyday errands and spontaneous adventures. With its compact frame and low step-through, the Flex is as easy to handle as it is comfortable and fun to ride. The powerful rear-hub motor from Promovec, with a full 55 Nm, delivers good speed and natural assistance, whether you commute in the city or carry a heavy load on an adventure.
The e-bike comes with Atran Velo racks at both front and rear, so you can customise your bike with a basket, panniers, a child seat or cargo boxes — as needed. The double kickstand gives extra stability when parking, even fully loaded.
The Flex is fitted with Promovec’s intuitive Graphic Slim D700+ display, where you can easily switch between 5 assistance levels and access the walk-assist function. Via Bluetooth the display connects to the Promovec e-connect app, giving you even more control and overview of your e-bike.
The wide handlebar and 20-inch Vertigo Speedster tyres give you good manoeuvrability and a secure feel in the saddle — perfect for both city riding and shorter trips out of town. With integrated Herrmans lights, hydraulic disc brakes and solid components, the Humber Flex is a robust and reliable everyday companion.
