I want to rent a bicycle in Belo Horizonte, in Brazil.
The default bike sharing scheme is only available in a limited area and has the main issue that you can only rent bikes for one hour at a time (1.5 on Sundays). Additionally, the same bike sharing scheme in other Brazilian cities has degraded significantly in recent years, meaning I'm not too hopeful about this one.
BikeMania no longer operates a website. They have two branches, both close to Pampulha, which is where I want to go for a ride, but a downtown location would be more practical. They charge R$10,00, R$20,00 (with gears) and R$30,00 ('triciclo família') per hour, which means they expect you to rent for an hour or two, not for a day.
SpaceJoy (thanks @Dorothy), also close to Pampulha, charges R$10 per hour for 'basic' bikes.
