oPinion-eT
idworx oPinion-eT - Touring bike with built-in tailwind!
Built on the proven frame geometry of our idworx oPinion BLT, the new idworx oPinion eT frame has been completely redesigned—without compromising the essential details that define every idworx bike. The standout feature is its advanced system integration: the powerful V10 battery is elegantly integrated into the down tube, offering an impressive 720Wh capacity for long-distance daily rides without frequent recharging.
The battery can be conveniently charged while installed via the external charging port or easily removed from below through the large opening in the down tube. Combined with the highly reliable Pinion gearbox (standard C1.6, optional C1.12) and the smooth, low-maintenance Neodrives Z20 rear hub motor, the oPinion eT delivers a quiet, efficient, and exceptionally low-wear riding experience.
For maximum versatility, the idworx oPinion eT can be configured with either 27.5” Plus wheels or 29” wheels, making it the ideal premium e-bike for commuting, touring, and long-range adventures.

idworx Stress Reducer steering angle limiter
effectively prevents the front wheel from turning over and thus protects against damage to the frame, headlights or even the shift cables and brake hoses, which can occur due an accident or if the bike falls over.
idworx Long Life Chain Rings
The Long Life chain ring we developed at idworx made of hardened stainless steel with an uneven number of teeth together with the extra-hardened idworx KMC E1 ePT chain and the idworx Rohloff steel sprocket, makes for unprecedented longevity. In our oPinion models we even fit our Long Life chain ring back and front. Chain tension requires less frequent checks - a pleasing consequence of a more wear-resistant drive.
