Italian bus bellows provider PEI Mobility has been chosen by Castrosua to equip its new range of electric buses based on Nelec body and realized in partnership BYD. The supply, announced by the Italian provider, offers a preview of the upcoming launch of an articulated BYD Castrosua model. The cooperation between the two companies, aiming at Spanish market, was kicked off in 2023 and involved so far only 12-meter models.
PEI Mobility is set to provide interior bellows characterised by an exclusive ergonomic design to ensure better passenger comfort.
The company had launched a new range of innovative, high-performance joints for articulated buses in late 2024.

“The hose guiding system for electric feeding is suitable for housing high-voltage cables and is hidden from outside thanks to the in bellow built-in extension, giving a clean aspect and an innovative design”, PEI underlines.


PEI adds that its “hose guiding system is patented about two features: the pulley helps bus movements giving high reliability and avoiding tensions on electric cables, then the leaf spring supporting the cables: this is composed of a multiple leaf (not a single piece as usual on the market) designed for easy and effective maintenance, as every section may be replaced without acting on the entire mechanism”.
Furthermore the internal bellows fixing to chassis is a patented system allowing fast assembly and disassembly and giving rigidity to the whole structure.
