Hi, I'm new to bike, have a dahon vigor d9 for few month, using it as recreation bike on weekend. Want ask a few maintenance question.
1. I think I need change the marathon Racer tire in 6 month time. Where can I find Marathon Plus or Panaracer Paselas 20"?
2. I'm using WD40 PTFE dry lube for chain. I heard paraffin wax lube is good, anyone know where to find?
3. Any shop to recommend for wheel truing? Or where can I buy the tool to DIY?
Thanks.

Found the marathon plus at roda link. Any other tire brand recommendations for 20" 406? Currently tire is 20x1.50, the marathon plus is 20x1.35. Do that mean better pickup but less grip?

I usually ride around 10-15km around my area during dry weather. If it is raining or road is wet, I wouldn't ride. Yes, I'm interested in the paraffin wax. My usual way to clean chain is just use WD40 spray, soak for 5-10min, paper towel wipe clean and apply dry lube. Is that enough to degrease?

Thanks.

I'm scare of uphill climb, leg is to weak. That's why need to ride more.
I like to keep my toy clean, little bit of TLC is needed especially when it is still new. There is some rust on the chain when I got it, as it is keep in store for some time.

A lot of sifu have spoken. I can give my beginner experience as I’m in your position last year in September.

We’re spoiled with choices nowadays. I funneled it down for you.
1. Don’t go the road of custom as you don’t even know your likes or dislike or your physical condition.
2. Get branded for better quality and assurance.
3. For bang of the buck , buy used.

I have myself a used dahon vigor D9. Gone through 700+ km with it since September. Most difficult time is the first month of ownership. Body aching every where. And also fell from bike cause very clumsy.
Fun part of it is:
1. Know some friends
2. Enjoy some outdoor and exercise
3. Doing some simple maintenance and add on (mud guard, lights, lubrication, cleaning ...)

Thing I don’t like about the vigor d9:
1. Rust at the nuts and bolts, even I don’t raid in the rain and store it indoor.
2. Chain also rusting. But I got a spare connex nickel plated chain ready.
3. It is not very portable like brompton that can put on floor and push around .
4. Creaking bottom broken. Spray some wd40 will quite it down for a few ride, but will come back.
