With the stock controller, each PAS level increases the maximum wattage sent to the motor, and simply cuts off when the top speed is reached. A cruise control option would be nice.

Welcome to the forum! Sounds like you are getting some nice range!

Thanks for the welcome Ryan! I was a bit surprised at the range, as some short hills we climbed were so steep that I was shooting pebbles and acorns out from under the back tire. For the last half hour I just rode around the neighborhood using only throttle because I wanted to drain the battery. If I had rode using normal power assist, I feel I would have gone a few more miles.

Yes, he definitely has that plate on upside down.  Are you going to use a 1/4 inch steel plate on your's? Just curious.

I ordered my RadMini 4 on July 31st, and it was delivered on Aug 21st.

I used a standard air chuck that I use on my car tires. It worked fine.

Looks like great fun! I wonder if a thermal wrap would have helped the battery?

Great info on the controller. I'm holding off on modding mine, but if I do, the controller will be first. Mine is the US spec version, and it pulls pretty firmly all the way from 0 to top speed, so I'm not really in need of more right now. The horn is hilarious!

Just saying hi for my first post. My RadMini 4 was delivered a week ago, and I've ridden it 91 miles (146 km) so far. The experience has been great so far, with the only mechanical issue being the frame joint creaking. The sidewalks and paths are a bit rough where we live, so I have not locked the front fork out, and I lowered the tire pressure down to 22 PSI (151 kPa) to deal with the bumps and cracks. Often the pavement just ends, and going from smooth to gravel or grass is a firm reminder that this is a hardtail bike!

I'm a former marathoner who now has metal plate and screws in my leg, and knees that are just worn out. This is the first time I've been able to ride in years without significant pain. My RadMini 4 is a US specification model with the 750 watt motor and throttle control, and it pulls quite nicely with the smaller diameter tires. Despite my knees, I've ridden up significant hills at power assist level 3 using in 4th gear. Mileage has been good, and I've gotten 41 miles (61 km) on one charge with heavy use.

I wanted a Rad rack but it was unavailable, so I bought a universal one and made my own vertical supports for strength. The original supports were adjustable, and I was concerned about the impact of bumps overwhelming the single set screw on each side of the rack. The new supports are one piece, and are attached to the inside of the frame stays to improve the geometry. I know Rad warns you not use use other accessories, but I can't buy theirs, and this is a necessity. On the bright side, the rack is stronger than theirs, and the higher position gives more visual balance to the bike.
