So users should probably check with their manufacturer first if they want to play it safe.Īnd of course you’ll want to check with your local regulations to determine if the device is considered illegal on public roads. Manufacturers will probably frown at the device’s use, or could even consider it a warranty-voiding action.

It also doesn’t require the user to open or modify the motor or drive system. Sick of hitting your e-bikes speed limit when you’re friken given ‘er the beans?! Want to smoke ya mates?ĭesigned, tested and manufactured in New Zealand, our Speedi uses a mechanical planetary gear system to increase your standard e-bike speed by 1.5.Ī nice feature with this method of “hacking” the bike’s top speed is that it doesn’t interfere with other measurements being registered by the drive system, such as torque, power, temperature, etc. I’ll let the Speedi folks describe the use case in their own words: That would effectively turn a 15.5 mph e-bike into a more thrilling 23 mph ride. It uses a small gear with a 1:1.5 ratio to slow down the speed sensor. The Speedi device tricks the speed sensor on the rear wheel into spinning more slowly, effectively raising the e-bike’s electronic speed limit by around 50%. When the e-bike reaches a pre-programmed top speed – as low as 25 km/h or 15.5 mph in many countries – the motor power cuts out and riders can only reach higher speeds under their own leg power or with the help of gravity. Many electric bicycles use a magnetic speed sensor on the rear wheel to measure the traveling speed of the electric bike. But a new device is making it easy to increase the top speed of electric bicycles without making any major modifications to the electric bike’s drive system. Electric bicycles are subject to various speed limits around the world, but the 25 km/h (15.5 mph) speed limit in places like the EU and Australia is particularly frustrating to riders who are in search of just a bit more “oomph” in their bikes.
