Bolliger & Mabillard, commonly called B&M, is a Swiss firm that designs and builds roller coasters. Based in Monthey, Switzerland, the company was established by engineers Walter Bolliger and Claude Mabillard and installed its first coaster in 1990. Over the following decades B&M has become well known among parks and enthusiasts for producing a wide range of high-capacity, durable attractions — today their portfolio exceeds one hundred installations worldwide.
Distinctive features
B&M trains and track are frequently praised for ride smoothness and consistent performance. The manufacturer developed recognizable train designs and a box-section track profile intended to reduce vibrations and provide durable alignment. Their restraint layouts vary by model: lap bars dominate on large seated coasters, while other types use over-the-shoulder systems adapted for inversions or unique ride positions.
Model types
- Inverted coasters — trains under the track, popularized by early B&M designs
- Hyper and giga-style coasters — focusing on height and sustained airtime
- Floorless and stand-up variations — alternative seating arrangements for different experiences
- Dive and wing coasters — emphasizing vertical drops or outboard seating
History and development
Founded in the late 1980s by two experienced engineers, B&M moved quickly from prototype to production. Their early 1990s inverted coasters established a reputation for tight engineering and reliability; several models from that era became templates that other parks replicated. Growth came through steady innovation in ride concepts and a reputation for build quality rather than aggressive marketing.
Notable installations and impact
Examples of B&M work include iconic park attractions that demonstrate different model strengths: early inverted classics, large hypercoasters known for airtime, and dive coasters with dramatic vertical drops. Parks choose B&M installations for longevity, guest comfort, and dependable operation, making the company a frequent partner for major theme parks seeking headline roller coasters.
Today B&M remains a benchmark in the industry: its designs are frequently cited for smoothness and low-maintenance operation, and many of their coasters are considered flagship attractions at the parks where they operate.
