1 year agoRe: The rear derailleur. Shimano Altus derailleurs are excellent. They are produced in vast numbers , used by many brands, and are durable. American custom bike manufacturer Rivendell speaks highly of the Altus rear derailleur.

1 year agoCool, thanks for this input Greg! I have been told similar things by the different bike brands… they suggest that the quality is high on Shimano parts, and the lower end models just weigh more or offer less adjustability but are still reliable. As a reviewer, I’m trying to communicate the differences in components and pricing, because there is a reason that the companies have different levels of hardware. It seems like some of the most ideal choices right now are out of stock, so companies are pivoting to similar hardware and just trying to maintain product availability.

1 year agoThe Radcity 4 motor is very quiet. That’s an appeal to me (though I don’t really like the drag when coasting). How does this new motor compare in noise level to the radcity 4?

1 year agoHi Tim! The planetary geared hub motors do tend to produce more noise than gearless direct drive, but Rad is using a higher quality motor here that is quieter than average. If you listen to the ride tests on this video or for the high-step version of the bike here, you can skip to the parts where I’m focusing the camera on the motor and judge for yourself :)
More and more companies have moved to geared because they are lighter, coast more efficiently, and provide more torque at low speeds. The regen feature of gearless hubs was neat, and they did tend to last a long time because there are fewer moving parts inside (just magnets), but the benefits of regenerative braking just didn’t seem to outweigh the costs, especially since it wasn’t very efficient. Perhaps we will see some combination of geared plus regen someday, but then cost could become an issue, since it would be so fancy and require a unique controller and additional sensors.

1 year agoRad City 5 Step Through or Charge Comfort? Is there a web address where I can find a head to head comparison? What’s your opinion on this choice? I already own the Charge Comfort and am buying a 2nd bike. Is the extra money for the Rad City 5 worth it? Thanks, Ed

1 year agoI own the Rad City Step-Thru 3 that I use for a daily commuter. With that bike I can “increase” the top speed to 25 miles per hour and to even faster if I change the wheel size to smaller than 26 inches in order to trick the controller into perceiving that I am not going as fast as I am in reality. I like being able to do this as when I am riding down hill – before I made these changes – the experience of riding would be very “jerky” as the motor cut in and out as I approached 25 mph and as I exceeded 25 mph the motor would turn activate regenerative breaking and make going past 25mph into a power lifting session.
My question is, what is possible (or not) with the Rad City Plus Step Thru? Can I increase the max MPH that the motor will help me get up to? I would not have to worry about the regenerative breaking – but I would like a motor that will continue to help me all the way up to 28 mph. Can this bike be configured to do that?

1 year agoHi Brian! Great question. I was not able to figure it out during my reviews, but apparently you can adjust some settings with the display to raise the top speed to something like 25mph. I’m not sure about the wheel size thing though. Here’s a link to the article where they figured it out, and these are the steps:
Hope this helps, please chime in with what you learn and if it works for you :D

8 months agoI want one I can tune or change to go 45 mph if anyone can sell me a bike that I can find that instruction to it I will buy one otherwise forget it 20 mph I can buy a moped for 300.00 that does the same thing
ReplyCourt
8 months agoHi John! There are some high speed ebikes out there, but they kind of skirt the rules being sold as “off road only” which could present a liability if used without turn signals and a moped license. I agree that there are some awesome gas and electric mopeds out there, which are setup as DOT approved. The Rad products, and other Class 1-3 ebikes are meant for bike paths. They tend to be lighter, have pedals, and can be ridden in places that mopeds cannot. Whatever you decide on, it’s great to have so many options these days :)

5 months agoDoes the RadCity 5 come in two different sizes? I am 5′ 10″.
ReplyCourt
5 months agoHi Julie! I think they only make this model in one size, but two styles (step-thru or high-step… and the high-step could be a little larger). I am 5’9″ and thought the RadCity 5 Step-Thru felt great. My inseam is about 30″ and I was able to raise the saddle enough to get full leg extension. I hope this helps :D
