TIER, which operates e-bikes and e-scooters across the Bath and Bristol area, will be rebranding as Dott from 29th August, with users having to download a new app.

From the end of the month, users in the West of England will be directed to the Dott app to continue using the shared electric vehicles.
Following the merger of TIER and Dott at the start of 2024, the business has now decided to integrate all TIER vehicles into the Dott app.
Despite the new app for the users and rebranded vehicles, the local team, operations and service remain the same.
TIER-Dott currently operates in over 400 cities across 21 countries.
TIER users have been contacted via email and app with all the relevant information to ensure an easy transition to the Dott app.
Switching to Dott is done in a few steps:
- After downloading the Dott app on the smartphone, users need to create an account.
- Then, all they have to do is add their payment details and they are ready to go.
- Users will also need to verify their driver’s license to ride an e-scooter.
If a user has already used Dott in the past, they can log in directly – if it’s been a while since their last trip, they’ll need to confirm their contact details.
The local team will also change all TIER branding to Dott, reflecting the transition to the new brand.
The joint team will carry out all operational work, such as battery changes, vehicle reworking, or rebalancing in the city.
Iqbal Ahmed, Head of Public Policy UK at TIER-Dott, said: “We are delighted to announce this step for the West of England and are confident that the integration of TIER and Dott will further advance shared micro-mobility in the region.
“This new phase brings benefits not only to the users, but also to the cities as a more reliable service.
“The aim of our shared service of e-bikes and e-scooters is to complement the public transport systems at a local level.”
