Assuming a coefficient of static friction of around 0.6, and a air-resistance coefficient of 0.172 for a rider and clothing and bicycle weighing a total of about 80kg (175lb), and assuming 70% of the weight is supported by the rear wheel, I get a maximum speed around 156 km/hr (97 mph)....
Is the Cd of 0.172 realistic? I have seen values quoted from Cd=0.4 for an upright TT cyclist to Cd=0.9 for a rider on a upright "city" bike.
The calculated Cd for the Varna Diablo [1] is in the range of about 0.06 to 0.08.
