"A woman, aged 35, also arrested, has been released on police bail pending further inquiries.
"House-to-house inquiries continue and officers continue to appeal to anyone who witnessed this collision, or anyone who saw a blue Citroen Picasso in the area shortly before, to contact us on 101."
Mr and Mrs Simons died at the scene of the crash on Lower Hanham Road.
The car was speeding moments before the incident and officers indicated for it to pull over, but were forced to follow it after it sped off. Moments later the car struck another vehicle before colliding with Mr and Mrs Simons's tandem.
Their families paid tribute to them in a statement, which said: "Both of our families are completely devastated by the tragic events that took Ross and Clare from us. A very special couple have been taken from us and we have no words to describe our loss."
