I already discussed this issue with my bike "Wrench master". I have a 2018 City Step-thru with the 46T chainring. Not big enough. You need a 52 T. Unfortunately for me I would have to modify the frame to get it to fit. The key is to replace the Step=thru model with the one featured if I can...

BKing. Good point about losing 1st and 2nd. In my case not an issue as I never except that one time ever been below 4th gear. The City is not a mountain bike. A City bike is used mostly flat (except if your in San Francisco then maybe one does need a 42T). The road bike guy I passed in PAS 2...

That is reason i wondered if I switched from a 46 T to a 52 T if my 5th gear would be like my 7th and I would have two more gears

Thanks for your response BKing. I have the 2018 City with the 46T crankset. I ride 95% on the flat for exercise. We have a 9 mile asphalt trail about a block away from cars that parallels a river. The city built it on top of the levy. that goes under all major streets and terminates near the...

Thanks EB I think you answered my question. There is a 52T chain ring I saw online that based on Sierra's formula has a final ratio of gear #7 somewhere around 122.6 as I inputted the other numbers. Wheel diameter - Tire size 26 x 2.125, 170 mm crank, Shimano 11-34 T - speed "mega-Range...

Hmm Sierra, Not sure I understand everything you said. What does "spin out" mean? Back 3 years ago before buying the electric bike I had a 24 speed cross-over bike. 3 gears in the front and a 8 gear cassette in the rear. Mostly I rode it in 16th-17th range and always had pedal resistance. If it...

Sierra. I tried your calculator with the following chain ring sizes. Results: 46 T on 11 gear = 108.5; 42T on 11T gear = 99.0 and 52 T on 11 gear = 122.6 I don't care that much about top speed. Would I like to get up to 25 mph? sure...Though at age 76 riding in a t shirt and bike pants don't...

Geno, I have a 2018 ( Retired living in San Diego I ride recreationally.) with the 46T and want to go smaller as I ride in 6th & 7th all the time and need 1 gear size lower. Maybe a 38 T. I'm 6 foot 1 inch 230 all up weight. Maximum speed in PAS 3 is 23.1 on flat ground. I ride mostly in PAS...

Thanks for the info EB. That is the reason the discussion is on a different crank set. Have you switched yours for a lower tooth gear?

OOPS!! MIstake ...Sorry. Edit previous The chain crank gear is a 46 T as reported by others The rear gear set cartridge is a "DNP 7-speed Freewheel 11-34 T. The "Freewheel" is what you want. I'm talking to Shimano this morning to see if they make a 10-32 T. I wonder if that old post was...

The issue is not the pedal gear, it is the cluster cartridge gears attached to the rear motor. The RAD City gear set is a 47 T (number of teeth on the largest gear # 1). Rad's # 7 is close to a 15 T. Last year a member reported that he changed his cartridge to a 36 T which changed the highest...

The issue is the gear cartridge. The RAD city has a 47 T. About a year ago there was a post about changing the gear set to a 36 T , in the set the high gear was probably a 10 T (T is number of teeth). I'm a recreational rider, averaging 1.5 days per week. Just turned 1,700 miles - 2 years old...

Will do Larry . Thanks for the suggestion

Adjusting the spokes: I had assumed the bikes were shipped to Seattle then opened up a tuned before reshipping to the purchaser. Velofix said 'not so". RAD has regional warehouses. Southern Cal's are in Los Angeles. The bikes are shipped to the the regional warehouses direct from China. then...

After the third attempt (bikes selling out in less than 5 minutes), I was successful ordering it in June getting on the road end of the month. Velofix set it up and extended a free 30-90 day tune up that RAD was offering when they were working together. I ride for pleasure and at age 74 was...

Third attempt worked - Hooray. The June 7th batch sold out in 3 minutes after the opening bell. I got my 10 year old grandson to do the "keystroking" as he is faster (lot faster) than I am...and between us we got it done. "Step-thru's " arriving here on the 14th. Thanks Mr. Gold for the 1859...

Yes you are both correct. Yesterday we took a trip to Newport Beach and rented 3 RAD's - City step-thru, Rover, and the folding model with the geared motor. The "City step-thru" does 90% of what the Magnum "cruiser" does and its $400 less expensive. We rode for two hours and received a $50...

Thanks Mister M for your comments. Motor/controller/battery: I assume that is a closed system and only an authorized mechanic can repair it. Question: where are most of these components manufactured - Canada or China? Is one better than the other?

Thanks MR. Tomorrow (weather permitting) we are going up to Newport Beach to rent a RAD City . Comments from an owner are very important and helps with the process. Speaking of RAD and "Velofix". Velofix will bring a RAD bike to your house or office for a demo ride so you don't have to take a...
