errrr..... exceeding 15.5mph under power means the bike becomes a motorcycle. It therefore needs tax, MOT, insurance, a full set of lighting and type approval; as well as a motorcycle license. Kind of pointless isn't it ?

Well we haven't bothered with all that to be honest. The 15mph limit seems rather crazy considering you can beat that speed under pedal power alone. So far haven't been stopped and the kits are quite discreet so hopefully shouldn't have any problems.

The clue is in the video title....'500W Electric Bike Kit Motor E-Bike Conversion - PART 2' If you had watched 'PART 1' first you would have seen the full setup & a general run through the kit.

@xenbay In the US, our national law is not more than 750 watts/36 volts, and no faster than 20 mph by motor power alone on a level road. 15.5 is certainly safer, especially if you hit a pot hole, but the bigger motors and more watts allow you to climb hills much better. For a steep hill, many people would still not be able to pedal up the hill with a 250 watt motor. Most can with 36 volts and 750 watts using a 500 watt motor though. I have both a 250 and a 500 and the difference is dramatic.

F the law

@niceboy60 Those cyclists don't look like your average cyclists to me. They look proper fit and into racing cycling with appropriate bikes no doubt. I'm telling you, 30mph is just not possible on the flat on a mountain bike or normal pedelec style bike. I run 2km every day and work out in a gym so I'm probably above average fitness.

[niceboy60]

@xenbay 30mph on the flat. Just not possible ???

.

please refer to this video women's cycling

.

Perhaps you are not as fit as you think

@niceboy60 If you need for some reason to go 30mph under power, then its not a bicycle you need, it's an electric moped and for that you need to get a license.

[xenbay]

@niceboy60 You're making light of situation. It's a serious matter when you have bikes on pavements and roads with 500W and higher motors. The police have a duty to make sure that doesn't happen to protect the public. And if that starts happening regularly it will reflect badly on all of us. The law is the law, it's not there to be got around or ignored. It's there for a reason. The restrictions were put there by consultation with experts and have a very sound safety reasoning behind them.

[xenbay]

@niceboy60 I'm reasonably fit and I've never yet been able to pedal my ebike (which is very light compared to off-the-shelf ebikes) 30mph on the flat. Just not possible on a legal bike. What you seem to be ignoring is that at present the law doesn't allow the motor to continue providing power above 15.5mph once you start pedaling. So once the speed hits 15.5mph you're on your own and pedaling without any power assist.

[niceboy60]

@xenbay you see fellow ?

.

You and law have allot to learn

.

The Hub watts does not mean nothing please refer to my video with ( my tuned 250w Stock )

@xenbay the max speed on this hubs is around 28 mph . If you pedal you might reach about 30 mph . Which means around 14.5 mph over the legal speed , You must be a real bored police officer you start stopping Bicycles for speeding . When there is video of Motorcycles showing of doing almost 200.mph . This bicycles does not pose a risk to the public as other vehicles do

[xenbay]

Just to clarify, here is the law at present on UK ebikes... maximum motor power rating is 250W..maximum speed is 15.5mph... power is allowed on throttle-only up to the limit, and on pedal assist the motor must cut-off when the speed of the bike reaches 15.5mph.
