The event is taking place as part of Bristol's Big Green Week in June, on the first weekend of the festival – the UK's first festival of environmental ideas, art and culture.
The Atmosphere Electric Bikes World Championship will be held on Sunday, June 10.
More than 10 top electric bike manufacturers will be taking part in the uphill race, competing for the Good Energy Cup.
The race will be compered by TV space comedy Red Dwarf star and electric vehicle fan Robert Llewellyn, and is being organised by electric bike specialist Atmosphere Electric Bikes, based in St George's Road in the city centre.
Before the race, Park Street will be transformed into a playground with children invited to take part in a giant chalking session, led by Drawn in Bristol.
And the Raleigh E-Bike Stunt Team will be making several world record attempts on College Green at 1pm jumping and performing on electric bikes.
Paul Rainger, co-curator of Big Green Week, said: "Big Green Week looks set for a record-breaking afternoon of fun on the Sunday, with stunts, races and all round entertainment.
"We're really excited to be hosting the first ever Electric Bike World Championship – and delighted that Robert Llewellyn will be with us to present the first ever Good Energy Cup."
Juliet Davenport, founder of Good Energy, said: "As the UK's only 100 per cent renewable electricity supplier, we are delighted to support the first ever Electric Bike World Championship. It looks like it's going to be a very exciting competition. I hope visitors really enjoy the event and are inspired to do more cycling themselves."
The afternoon's street entertainment will round off with an attempt at the world's biggest ever micro-ceilidh on Park Street at 4pm.
Electric bikes use low voltage motors and technically advanced batteries to boost traditional pedal power.
This means that you can cycle along as normal, losing none of the enjoyment and the motor will help you when the going gets tough up hills.
Charged from mains electricity, they have a very small carbon footprint, producing 29kg of carbon dioxide a year for a 20-mile daily commute to work, compared to 1670kg using the average family car and saving over £3,000 per annum in running costs.
