Hi

You need Normally open version.

To clarify, if the MT5e model says it's "Higo-Opener" then it's the wrong one? 'Cause that's what I bought and is finally about to arrive ... from Germany...

Thanks.

You need Higo closer, normally open.
Opener is the wrong one.

Thanks for the reply JTK77. is this on a Rad Mini ?  Tony.

Rhino (/Rover).

Quote from: Tony on March 19, 2021, 12:56:09 PM
With the extra speed of the upgraded mini. I find I am pedalling like crazy when 20 or more mph. Would changing the cassette or front chainring to a different size slow the pedal rate down? I would like to pedal more at higher speed in 7th gear. Has anyone tried this ? Any suggestions?   Tony

Getting ready to swap Bolton 750w motor into my Radrover, and have read adding a little extra white lithium grease to the gears is suggested.
Anybody know what grade should be used, or if it matters?
I've found both NLGI 1.5 and NLGI 2 grade white lithium grease.
Thanks

The best best option is Mobil SHC 100 (red). Mobil-28 is also good.
I'm using SHC100.

Thanks. Should I remove, wipe off as much as I can of what is already on there or is it ok to mix?

Better to wipe off most of the old stuff.

About the 60V 40 amp sine wave controller; are you selling those? The unit in the picture looks a lot like the Electro Bike World and Bolton trapezoidal wave controller... is that a coincidence, or are you using the same chassis?

This prototype is KT made unit slightly modified sine wave unit. Yes the body is the same. This may not be the same type as final product 😉
The project has suffered some difficulties as factories are filled with orders and MOQs has been raising too. Its talking more time than anticipated but will be ready some point.

Wow you really ARE a party pooper!  I imagine you wear a helmet, shoes with steel toes, motorcycle leathers, gloves, and wrist, elbow and knee guards when you ride your bike!  With all due respect, sir, my bike has a class 2 sticker on it, and I am CERTAIN few cops would have any idea what that means, and how it may apply to an ebike, and the law, and NONE could tell the difference between a 750w and 1000w motor, visually (nether can I!).  Additionally, for your edification, a 750w motor and a 1000w motor likely will compete directly in speed.  More watts does not equal more speed, it equals more torque!  If you want speed, you increase the voltage.  As I have explained, I ride on the beach (legally), and the extra umph of the 1000w motor gets me through soft sand much better, and does so with no noticeable increase in speed.  Now, given that I have a 1000w hub motor in rear, AND a 1000w hub motor in front, I may be stretching it a bit, but heck, for me, that is the fun in this sport/hobby/pasttime.    Interestingly, even RAD advertises their motor as 1000w, and so I can say that i have the same wattage motor as the manufacturer states is on stock bikes!  You enjoy yourself, safely, and I will do the same!  I bet I have more fun, though!

Do yourself a favor and buy a true 1000w Baffang hub motor...

How about the issue of legality for those of us who live in the United States?

In 2002 US law HB 727 was enacted by Congress and defined "low speed electric bicycles (like the ones currently sold by Rad Power Bikes in the US) as non-motorized vehicles not subject to laws requiring licensing, insurance and helmet use (among others) as long as they had electric motors of less than 750 Watts (~1 horsepower) which couldn't propel them at more than 20 MPH on a paved level surface with a 170 pound rider solely on motor power alone.

15 U.S. Code § 2085 - Low-speed electric bicycles and 16 C.F.R. Part 1512 went further in defining legalities, particularly as they applied to manufacturers. These later regulations might leave a bit of leeway in terms of what kind of modifications individuals may make to their bikes after they buy them, BUT THE 750 WATT/20 MPH MAXIMUMS ARE CAST IN STONE, anything more is a moped, motorcycle or some other kind of motor vehicle subject to all laws governing those classes and their operators.

Our Ebikes might be very hard to get licensed as road legal motor vehicles as their construction and and components might not meet the more stringent performance/safety testing requirements of those higher speed machines. 

Violations can get very expen$ive, and result in confiscation of contraband Ebikes in some localities.

Sorry to be a party pooper, it's just the law (and our cohorts in Canada and Europe are faced with even lower limits).

So why do 100 Watt motors exist? They would be legal for use on private property (your back yard or 5000 acre ranch in Montana) or by the military or other government agency. The MIGHT be legal for use "off road", on public/BLM/OHV park lands in some states if not specifically excluded from certain areas. The federal laws just prohibit their use on public roads, and most state laws would exclude them from use on most public trails as they would not be covered by the non-motor vehicle exemptions sometimes granted to Ebike classes like 1 or 2.

G062.1000 is faster winded motor compared to G060 series (even if compared to fastest winded 6 turn version).
I have the 1000w motor runing 60v 40A at the moment.
Also 1000w motor is legal where I live under EU legislation.

Quote from: Altema on March 07, 2021, 08:10:56 PM
Nice! What is the cost, and are you planning a 72 volt version?

These will be 17s Max but who knows the furure.

Just tested my proto design plug n play sine wave 60v 40A Rad controller kit. Order in Factory.
This unit is modified to L10 motor connector as I have the G06.1000.DC motor installed.
Also coming L10 ready sine wave 60v 45A kit with  UKC-1 display. Order in Factory.

JTK77,

Am trying to identify the Galfer rotors that you used but I am not sure of the exact model. F223/R203 do not give me any results.  Could you please advise me? Also, did you purchase them direct from Galfer?


Thank you,

George

Purchased mine locally.
Front is DB007W, adapter Galfer SB003
Rear is DB004W2, adapter Magura QM09

Hello!

Jumping in head first with my Rad Wagon 4 looking to upgrade the brakes.

I like the Magura mt5e Option, has anyone here used Magura on their Bike?

I need to know if I need the OPENER or CLOSER HIGO connector lever type, because its a German company the translation is a little off...

CLOSER = NORMALLY OPEN

OPENER = NORMALLY CLOSED

So does my RadWagon use "NORMALLY OPEN" or "NORMALLY CLOSED"?


Thank you

Hi

You need Normally open version.
I have installed MT5e's with Galfer rotors f223/r203.

The Bafang model number is RM G060.750.D 06
Rad controller limits the motor power. The Rad motor internal RPM limiter limits the speed.

Is there any stamps on the motor (inside or outside) where I could identify which model the motor is? Just being curious and interested in learning how the ebike systems work.

The meaning of Bafang model markings:
G060 = casing identification
750 = nominal rating
D = freewheel (DC = freehub)
(6) = winding identification (smaller is faster, no it directly equal to KV)

All Power versions within same casing series are swappable.
Rated model not possible to say what from casing as OEM customers can have custom labeling or motor core can ne swapped.
Rad has done both. In the past casing swap (+sticker) and nowadays custom labeling.
KV can ne identified by no load speed (wheel of the ground full throttle) If you have the throttle.

I have one last question, I ordered 2 motors, one from Bolton and one from Electro Bike World, the one from Bolton is marked RM G060.750.D 06 with a little sticker with 26"/700c/28" BLDC for e-bike A4 and the one from Electro Bike World is marked RM G060.750.D 06 1 with sticker reading 20" BLDC for e-bike A5.
Does the "1" at the end on the second motor mean anything?
Do you know if these motors are identical?
I'm guessing they are but figured it wouldn't hurt to ask.

Thanks!

I have not aware If the "1" has some relevant meaning.
The indication of 20" wheel well describes the higher KV of that motor. The way you can compare these motors once installed is to set wheel diameter to same value on both bikes. Set speed limiter to 72 km/h or on stock controller Set wheel diam. to 20". Run bikes full throttle (full batteries) rear wheel of the ground. Compare Max speed values.

Thanks, I'm pretty new to this, 1 is going on a 20" wheel bike and 1 on a 26" wheel bike, if the one marked 20" has a higher kv,  would it give more low end torque on the 26" bike?
I'm trying to figure out which motor to put on which bike. 
Thanks so much

Yes. Higher Kv is higher speed. So putting that on 20" bike will even the differences (speed and torque) between the bikes. Not necessarily make them exactly identical though as Kv differenfe may not 100% compensate wheel size difference.

Has anyone replaced the bars on their bike with a flat bar? I don't like being so upright so would like to lower the reach on my RadRover ST. If you did replace your bars, what bar did you use? Also, are the bars 31.8mm to 22mm?

I hyvä replaced the stock with PRO Devil Riser Bar Ø31,8mm 780mm.
