TurboBrake FlexiHose is a durable hydraulic line (fitted hose) for eScooter brakes.
This hose was inaugurally introduced on later model Teverun Fighter models which is the only known common make/model eScooter that has this type of hose factory fitted, paired with the HB427-4M calliper.
Fabricated with a braided steel mesh, having slightly larger outer diameter than typical BH59 hose.
Hose fitted factory crimpedTEKTRO style connector with o-ring (7mm OD x 1.5mm cross section).
Available in choice of three fitted hose lengths and separate coupler:
150mm (typically for extender purpose, used with coupler/joiner).
1280mm (1.28m, typically for front).
2100mm (2.1m, typically for rear).
Coupler/Joiner.
Notes:
First product image shows flexi hose (right hand side, silver crimp). Left is typical BH59 hose. 2nd product image shows the complete hose end-to-end. Lengths are measured end-to-end including that of the crimp (to the o'ring to be precise).
The coupler is custom fabricated for eSN and currently under production (CNC machined). Often bike shops will have them. Prototype images below, currently under test expected Q4 2025 (likely October):
For Teverun Fighter raised handlebar:
With routing on newer Fighter models through front center of stem, use the 150mm hydraulic flexi-hose and coupler to extend each lever (total two hose + two couplers)
And M8 prepared leads for other instrumentation as necessary. Noting a conversation cable is planned for the TurboTap Light and Horn Switch (with slider turn switch mechanism) which will extend the length of that cable.
Lengths for front and rear were derived from that of NAMI Logan 4-Piston (Burn-e) which is the most generous of all common 11" wheel scooters. Observed Teverun adopt 1230mm (50mm shorter) and 2100mm (identical) on early model Fighter Supreme 7260R. In all cases check / measure length of your own build.
Hose connectors are capped (sealed) and pre-filled with fluid.
