March 18, 20242 yr the cherry on the cake is the Eggrider v2, which means I can pedal up steep inclines without losing my initial speed Eggrider is not the upgrade. Controller is. Eggrider is just a display which you have there with new controller as a combo. It is sold to you because old LCD is not compatible with new controller. If what this guy say is true and your motor is rated 500W then your bike is illegal. If you have twist and go throttle, then your bike is illegal. If your motor doesn't cut off at 15.5mph/h, then your bike is illegal. - what's not to like? I wrote what I don't like... The real question is why did you choose your bike over other bikes available on the market. For example over Santana 3 or Wisper 705.
March 18, 20242 yr Those Rads are fitted with a G060 or if lucky a G062. According to the Bafang workbook the G062 is rated at 250w and 500w and 750w and 1000w. They're different versions of the motor. You can't convert one into another. You can only replace one with another. If it has 250w written on it, that's what it is.
March 18, 20242 yr They're different versions of the motor. You can't convert one into another. You can only replace one with another. If it has 250w written on it, that's what it is. show me where they are different.
March 18, 20242 yr show me where they are different. The most important difference should be the number engraved on motor. 250W or 500W or 750W or 100W.

March 18, 20242 yr Hi guerney - Top speed has increased, although not by loads, however, when I free-wheel down a steep gradient, I can go way over 15.5mph! Appreciate the input. Ride Rad Utilising gravity after the cutoff 15.5mph isn't illegal, reminds me of riding a motorbike again, only much slower. https://vimeo.com/874431040:44s Is there any chance you could upload a photo of the engraving or/and label on your hub motor?
March 18, 20242 yr Here is a good example of how Bafang rate their motors. Same motor on the specification sheet with 3 different power ratings depending upon how many volts are applied to it. So this particular example of a G060 is rated at 250 watts and 350 watts and 500 watts. https://bafang-e.cn/oem-area/components/component/motor/rm-g060250350500dc/
March 18, 20242 yr An Eggrider can't do that. A 250w bike is always a 250w bike no matter what you do to it unless you change the motor. You can convert a legal bike into a non legal one by releasing the speed limit, or you can covert a 250w bike into a 750w one by changing the motor. In other words it's the motor that determines the power rating and legality of the bike, not some fancy interface that dies the same as what you can do without it. I have no idea what you are trying to say here.

The exterior dimensions are for the case, but what's inside the case is different for the different versions. You get different windings with different wire diameter and different number of turns depending on the voltage, the speed and the power. It was the same with the older BPM and CST motors. The 500w was completely different to the 250w one inside and there were about 8 different speed versions of each power. They get the different speed by the different number of turns and strands on each pole. In engineering terms, you could have two motors that were identical in all respects apart from the way the poles were wound. One could have 8 strands with 8 turns, making 64 loops of wire, and the other could have 16 turns of 4 strands making 64 loops. Power is torque times rotation speed and torque is proportional to current. The latter would turn at twice the speed of the former, so would make twice as much power as the former if they ran at the same current. This is why you often see different power versions of the same motor or bike. The 250w one is designed for 15.5 mph, the 350w is designed for 20 mph, and the 1000w one for 30 mph. The 250w one might get thinner wire to save money because its resistance at the lower current would be less significant. It's generally desirable to keep resistances low because it affects efficiency, so in the above cases, the manufacturer would be able to claim high efficiency for the 250w version, which is a good sales point.

Hi Guerney - I'll take a photo and post it tomorrow (19th) Ride Rad
March 18, 20242 yr In order to travel south, south east out of town from here i need to take bendy 2 lane b unlit country roads with tall hedges and national speed limit, Not really an option on my 'city bike' and at night simply a frightening prospect, a comparable speed to other road users is a must for safety reasons, my current option for one destination is to simply take a 12mile? detour via tracks and slow bumpy paths to travel 6 miles. only 3 of which are on hazardous bendy rds Now my current bike would not be safe at any speed higher than 15mph, but the next one, i might even be convinced to ride rad after all. ....
March 18, 20242 yr Bloody bright lights fore and aft are safer on bendy country roads, lit or unlit - I can hear cars slowing down behind me, because they see the red flashing glowing foliage on the bend ahead of them, wondering what it is. Very bright headlights illuminate foliage beyond the bends, preventing vans cutting across corners and heading right at me.
March 18, 20242 yr Author I think the sturdiness of the Radrunner is a definite plus factor, the downsides? The weight Making turns at slow speeds But that's about all I can comment on really, I just love the radrunner.
March 18, 20242 yr The specification sheet that I linked to is for a motor with one winding suitable for a 26/700C/28 wheel. You can tell that because the weight is 4.1 kg. If the specification sheet was for different windings then it would say so and the weight of the motors would be different due to the different amount of copper. They are rating this motor at: 250 watts at 36 volts 350 watts at 43 volts 500 watts at 48 volts They have done exactly the same on the specification sheet for my G020 and it has got nothing to do with the wind. They are just trying to show their motors are compliant in the various global markets. We all know that these motors can be run at far higher levels than what is printed on the motor.

March 18, 20242 yr Author I got bored watching it because he kept trying to justify the eggrider is just to improve the hill climbing ability. When everyone knows it turns a 250w ebike into a 750 watt e-bike. AGS - Some folk think that torque is more useful that top speed, I am one of those folk.
March 18, 20242 yr If what this guy say is true and your motor is rated 500W then your bike is illegal. Indeed. But the video, which does promote the RAD, does not make clear whether its UK road legal.
March 18, 20242 yr From the research I did ( a lot!) It seems like legality of the whole thing completely eluded you despite all the effort you put into research. EggRider is a derestricting device and as such is illegal. You should not really promote it here as it is against forum rules. BTW £120 for LCD display is a robbery in bright daylight. I did not see a bike that has all the attributes that the Radrunner has: Customizable Utility Bike Proven electric motor Robust frame Fat Tyres Single Deralier (Less to go wrong) Premium manufacturer Coolest looking e Bike available (my opinion) After-sales service available 2 Year Warranty All frames are robust. Single speed might be acceptable on bike that cost £500. What you have is an illegal moped, not an pedelec.
March 18, 20242 yr I have no idea what you are trying to say here. The Eggrider can make a bike illegal by releasing the 15.5 mph speed limit. That's all. You can get all the power you want without having to be illegal.
March 18, 20242 yr The Eggrider can make a bike illegal by releasing the 15.5 mph speed limit. That's all. You can get all the power you want without having to be illegal. It also derestricts throttle.

March 18, 20242 yr It also derestricts throttle. You can do all that without an Eggrider. It's just an interface to make it easy for people that need it to be easy.
March 18, 20242 yr You can do all that without an Eggrider. I am sure you are right. But it is more profitable to sell display for £120
March 18, 20242 yr Author Indeed. But the video, which does promote the RAD, does not make clear whether its UK road legal. Well, here's the thing as far as I am aware - the motor is labelled 250w, and I do not exceed 15.5mph (except when free-wheeling down a steep incline) so you may be correct - technically that is - but I am fully insured on my Radrunner, and I also think even if I am involved in an accident (heaven forbid!) I would be legally safe. Appreciate your input Ride Rad

I know what the Eggrider does for the torque , and that it makes a huge difference, whether the Radrunner is legal is another matter, as for a single - speed version, you failed to omit the advantages this has for future maintenance costs. As for the debate concerning whether it is, or is not a pedelec, sure the clue is in the name? Ped = Pedal and elec = battery powered, surely the Radrunner has both attributes?
