West Midlands Police said Ibrahim, 21, initially struck Mr Jones and then sped up to hit him again, causing the cyclist to come off his bike and collide with a concrete bollard.
Liam Jones, 22, suffered serious chest and abdominal injuries and died at the scene after Abdirahman Ibrahim drove into the back of his electric bike twice in Sheldon, Birmingham.
The force said the brothers then split up, with Abdullahi Ibrahim returning to the car, which was later found parked in Hingeston Street, near the Jewellery Quarter.
Ibrahim then fled the scene and parked his car in Golden Hillock Road, Sparkbrook, while his brother called for a taxi to take them home.
