PT Pro gear shaft for the Segway PT - optimised and reinforced

Suitable for:
Segway Gen1 Segway Gen2/i2/x2 Segway SE/i2/x2

The PT Pro gear shaft for the Segway PT is equipped with an optimized bearing fitting ring to prevent the shaft from shrinking after use and to extend the durability to the maximum. This means that a gearbox revision is no longer necessary!
The flange plate has been reinforced by 2 mm from the original, from 6 mm to 8 mm. Therefore it resists even harder blows. The plate does not warp any more. This avoids the cause of wheel imbalance.
The wheel bolts can be changed from the outside by turning them in and out. This means that the bolt length can be freely selected and the use of spacers (spacers, wheel spacers) is possible. Wheel studs are not included in the scope of delivery! Order separately!


This creates flexibility in the choice of wheel - tyre - combinations. The possibilities with our wheel spacers (article number 80422, 80423...) allow new vehicle variants.

With this gear shaft high quality Segway Gen1 gears can be converted to Segway Gen2 and Segway SE.

The special PT Pro Spacers in 10 mm and 20 mm with own centering are simply put on the longer bolts. The track is widened easily and quickly and rims with other offsets can be used.

A gear shaft that leaves all possibilities open.
