Tramper - off road mobility scooters

We wish to procure 5 Tramper type mobility scooters for use in a network to operate across our geographic area, to improve access to the countryside for those who are currently unable to due to physical barriers. We intend engaging with Lake District Mobility the sole regional provider of network support for this type of initiative. The network requires a single type of vehicle to join (The Tramper by Beamer Ltd) which might require single supplier negotiation.
