The Flex LT is a longtail version of the regular Flex. Here you get even more room and the possibilities are many. The frame’s optimised design makes it easy to get on and off. The double kickstand with Smart Lift makes parking child’s play — even with a high load. A flexible AVS+ system at both front and rear lets you fit e.g. a basket, child seat, panniers, cargo boxes, etc. The functional rack allows two child seats at the rear or fitting a double seat (optional).
The Humber Flex comes with a user-friendly graphic display that connects via Bluetooth to Promovec’s e-connect app for a more personal riding experience.
The display has 5 assistance levels and a built-in walk-assist function, for example if you need to push the bike up a hill. A basket can be fitted as an option.
The model is available with both 3" tyres (Flex) and 4" tyres (Flex+).

Description
Longtail Flex e-bike with wide tyres and maximum capacity
The Humber Flex LT+ is a powerful, spacious longtail e-bike with wide 4-inch tyres, made for those who want ultimate stability, comfort and flexibility in one bike. The sturdy frame and long rack make room for two child seats or a double seat, while the AVS+ system front and rear makes it easy to add bags, baskets or cargo boxes.
The wide tyres give secure grip and comfort — whether you ride on asphalt, gravel or cobblestones. Combined with hydraulic disc brakes and a double kickstand with Smart Lift, the Flex LT+ stands stable in every situation — even fully loaded.
The powerful Promovec rear-hub motor with 60 Nm of torque easily pulls both you and your load forward, while the centrally placed battery ensures good weight distribution and a long range. The user-friendly graphic display connects to the Promovec e-connect app via Bluetooth, so you can customise and monitor your ride digitally.
