Cyrusher Rumble Review

[Bizdustry]

I made a review about the Cyrusher Rumble. If you have any suggestions or feedback on how I can improve my videos please let me know.

But, what a great bike for the price. Retails for under £1000. Over 100 miles or range, and a top speed of 28mph. Although, this bike isn’t legal to be ridden on UK roads - it’s not compliant with EAPC legislation so would only be allowed to be ridden off road with the land owners consent.

You could maybe add restrictions to both the motor and controller to make it road legal if you wanted to use it on the road.

What do you all think?

My understanding is that it's completely legal if you set it to 15.5 mph, which is what it comes set to. You should show whether it is or isn't legal and why.

The motor wattage exceeds 250watts and the bike is fitted with a throttle. According to the EAPC regulations, its not just speed that is taken into account. Perhaps I should gave explained this better in my review, thanks for the feedback. Riding an electric bike: the rules - GOV.UK

Motors are allowed to exceed 250w output, if that's what you mean. There's no limit to how much power they use or make. The only requirement is that they can't be rated at more than 250w. The Cyrusher Rumble motor has 250w written on it, so it's rated at 250w, which is legal. basically, if it has 250w written on it by the manufacturer, it's legal, regardless of anything else. The control system must limit the speed to 15.5mph.

so because the motor is limited, and peaks at 250w it’s legal? Guessing the moment it’s not, is when someone removes the restrictor.

But how do manufacturers get away with sending throttles in the assembly kits? As adding a throttle to a EBike makes it illegal without it being registered as a light moped with all the correct documents?

If you derestrict it so that it goes over 15.5 mph. It's illegal, regardless of the motor.

You still don't seem to understand the difference between peak power and rated power. Rated power is the power written on the motor, and that number must be no more than 250w. Peak power is the maximum power it can make. There is no legal limit on peak power.

The Chinese manufacturers sell their bikes in many markets. In some markets, throttles are allowed, so they put the throttle in the box for them to fit if they want it. Also, you can fit a throttle in the UK if you get the SVA test done, which costs about £100, but there are a few special requirements for that test, so you'd probably have to do some minor adjustments to your bike to pass, like put some protection over cables, ball-ends on the brake levers, a bit of tubing on the front mudguard, mirror, bell, reflectors and things like that.

Some bikes have controllers that use a throttle as a speed or power controller while you're pedalling, which is also legal. The Mirider and Engwe L20 Boost are like that, though they use a boost button rather than twist throttle. My bike does it with a twist throttle, which is a feature of KT controllers.
