    Changing RadMini gear ratios

    When the DNP tool is split, you have finished all the hard work. The rest is easy. Take the rear wheel off the bike. I had already "broken" my chain when I replaced the tires, so I just unhooked the master link and dropped the chain. Disconnect the motor electric plug, loosen the axel nuts...

    Changing RadMini gear ratios

    Once I determined that the tool would have to be split, I dug out my 30 year old Dremel tool and got to work. My Dremel uses the small 15/16" diameter cutting wheels, and I had some #409 wheels on hand. They worked fine for this job. I used one wheel on each side. Cutting the DNP tool was...

    Changing RadMini gear ratios

    Putting my money where my mouth is...I ordered the DNP 11-28T freewheel and tool. For the benefit of those who are a bit nervous about making the swap, I will document the installation of the freewheel with some (hopefully) helpful photos. First up, a look at what you get when you order the...

    Changing RadMini gear ratios

    Thanks for your comments, HarryS. Yes, I have read the reports that the DNP freewheels are not strong, and tend to wear out quickly. Even so, they are really the only available choice if a RadMini owner wants to reduce pedal cadence by swapping freewheels. The low gears (1st and 2nd) on the...

    Changing RadMini gear ratios

    New RadMini (2018 model) owner here. I find the discussion in other threads about changing gear ratios interesting, because I too would like to slow down my pedal cadence. To do this, as I understand it, you can change either the rear gears (the freewheel), or the front chainring, or both. The...

    Slick or Street only replacement tire/tube for RadMini?

    I got my Sunlite XLs mounted on my bike. Wasn't too bad a job if you've ever changed bike tires before. Biggest hassle is getting the rear wheel on and off (if you don't have a service stand to hold the bike - I don't). I didn't want to turn the bike upside down cuz there is so much stuff on...

    Here's one more possibility that has been mentioned on this forum. Kinda pricey - watch for them on sale? (Link Removed - No Longer Exists)

    Slick or Street only replacement tire/tube for RadMini?

    Good timing with your question. I just received a UPS package today with 2 tires and 2 tubes for our RadMini. We have only had the bike for a couple weeks, but I was already getting tired of the noise, vibration and increased drag from the knobby tires. 90% of my riding is on pavement. The...

    Known Issues & Problems with Rad Power Products + Help, Solutions & Fixes

    This may have already been mentioned, but I searched and could not find it. When riding your RadMini, do you get a "creaking" noise from the area of your handlebars? Ours was making that irritating noise, so I investigated. I found it was coming from the handlebar stem (the tube that slides...

    Any RadMini people out there

    This is good advice, except I found there was very little actual room for adjustment in the handlebars IF the bike seems to be "too tall" for your height. When I adjusted my bike, I immediately set the handlebars to the lowest position, because they were way too high for me. I would actually...

    Any RadMini people out there

    I'm not an expert on this stuff, but I have noticed a few things about our RadMini that seem a little different than most bikes I have ridden. First, the bottom bracket seems to be higher off the ground than "normal". Because of this, I had to raise the seat up higher to keep the distance...

    Any RadMini people out there

    Could you provide the source for the larger chain wheel? I'd like to add one to our RadMini but unsure what or where to buy. Thanks!

    What Gear for pedal assist?

    We just got our 2018 RadMini a week ago. I've been out on it every day, getting used to how it rides. We have two other eBikes. One is a 3-speed Nexus IGH cruiser style bike my wife rides, and the other is a 8-speed tadpole trike. Both of them have 750 watt mid-drive (BBS02B) motors. The...
