Hi, Is Park Tool PPL-2 safe to use in an ebike motor that has some residue left from the original white grease? PPL-2 is a darker green thick'ish type of grease. I'm replacing a bad 500w with a spare and swapping a 750 to another wheel. Both seem dry inside. No local stores have the...

Hi, I've got a Rad Mini 4 with a 35a upgrade and a 750 OEM upgrade. Also keep a spare wheel with a stock Rad 500 that I swap in the 500 for longer less hilly/technical rides. Still using the stock 48v 14ah battery. With the 750 installed, got 17.5 miles on a mostly dirt trail that was maybe...

I've got a Rad Mini 4 with the upgraded 35a controller and display. I'm upgrading the motor to either 750 or 1000. Still have the original 48V 14.0Ah battery. How much quicker should I expect the battery to drain? I have a spare wheel with a 500w motor I can swap in for longer rides But would...

Anybody have experience with ordering direct from Galfer? Placed an order 2 weeks ago for items posted as available. After they accepted my money, then sent an email saying some items are backordered till Feb 2 when they expect a big order. I called today (Feb.3) and they said they may get a big...

Hi, I'm planning to upgrade rotors on my Rad Mini 4 from the stock 180 to 223 up front and 203 in the rear. The 223 disc and post linked below were both suggested to me on this forum. This is the first time I'm upgrading rotors. Removed and installed enough of them, but never upgraded. I...

Hi, Anybody have experience with both a flat Jones H bar and one with a rise? Does the rise make that much difference with regard to posture? Wondering if my might feel more confident with a flat bar. I'm 48 and have had back issues keep off my bike a lot over the years. But I want a fun ride...

Hi, I'm planning to upgrade my Rad Mini 4's stock brakes soon and want to learn what I need first. If any of this is possible... Since the Shimano (cut-to-order) 355/365's aren't available right now, I'm looking for something I'll need to cut and bleed. Preferably, something that's not lower...

Hi, Anyone know where to find 10 pin extension cables? It's probably fine, but has some tension on it after the upgrade due to the one sided placement of the controller's output cables. Thanks

This is for a new Rad Mini 4. Replacing some of the button head screws I stripped with an old hex bit. Using the same silver 10.9 grade screw, but with socket heads instead. Was about to apply a drop of Park Tool's TLR-1 when I noticed the note stating the AP-1 primer is required for anything...

Hi, Some of my old hex bits damaged a couple screw heads. I want to replace the screws before they get stripped even with a new bit at this point. Does metal type matter? I don't want to get something that's too hard and end up stripping threads on the frame, but I'd like to get something...

Less than 10 miles on the bike. It squeals over about 3-4" section of the rear rotor. I cleaned them yesterday. Will try again tomorrow maybe with acetone. Removed front and rear rotors Soaked rotors 20 minutes in 90% alcohol, then wiped thoroughly with lint free cloth Wiped pads down with 90%...

New Rad Mini 4 with mech brakes. The rear was squealing bad over about a 3-4" section of the rear rotor. Have rode a total of 3 miles. Removed front and rear rotors Soaked rotors 20 minutes in 90% alcohol, then wiped thoroughly with lint free cloth Wiped pads down with 90% Sanded rotors and...

Changing out the 3.3" CST tires with 4.0" Mongoose tires. Struggled more than any tire I've installed, but got it on the rim with the tube and Tannus secure inside and on the rim. I inflated the tube slightly beforehand and it was fine. After installing the tube and getting the tire fully...

What rotors should I consider for a 2021 Mini 4? I plan to upgrade the controller and motor when parts are available so I want better brakes in place ahead of that install. I've never upgraded rotors so I only know what I've read which includes the usual conflicting info. I'll mostly be riding...

I'm a thinner guy and my helmets have always sat a little more loosely than I'd like. I currently have a Smith Convoy with mips and the wheel tightens it snug to my skull. I keep the straps as tight as I can without pulling the helmet too low, but when cruising downhill over 20 mph, my helmet...

The Mini 4 currently ships with 3" tires. Are the wheels compatible with 4" tires? Makes sense that thinner tires are easier to maneuver and wider can be a softer ride, Curious if I might enjoy the smoothness of the 4" tires at low pressure more than 3".

What's the performance diff between Shimano's 355/365 brake system and Juintech (Bolton's) calipers? Can't find Shimano or anything like it since summer 2021. We can adjust the levers with Shimano, but not with Juintech. If Juintech is not truly hydraulic, then is the primary difference that it...

Would Stan's sealant perform better than Flat-out on a Rad Mini 4 with tubes? If performance is equal, is Stan's easier or harder to install? I'll mostly be riding gravely campgrounds and worn trails with the kids. I purchased Flat-out, but didn't install yet. Stan's seems much cheaper and...

About how much weight could be removed from the Mini 4? Rounding up, we can say... Battery is about 8lbs Motor maybe 15lbs Wheels/tires about 3.5lbs each for a total of 7 If the M4 total is about 68lbs, then the bike minus battery, motor and fat tires it's about 38lbs. Which is still heavy...

Hi, Any taller riders using the Mini 4? Any issues crouching over? I'm looking at the Mini 4 as I wait for my return label on the RR6... that's really a great machine, but too much bike for my needs. I'm 5'12" or just shy of it (48 yrs old) with legs measuring about 31.5 based on Rad's...
