I used a 100T chainring when I did my 1x9 conversion. It worked really well, but I do not like the weight in the back wheel anymore. In the meantime I have bought a mid-drive Qulbix and will be working on a change of the double chains. I tend to ride quite fast and I cannot pedal more than...
ok, got it sorted out now: the controller was cutting off at 52V (undercurrent). I have increased the battery size to 26S6P and now it works very well.
The power is insane (150NM torque), which meant that I did an uncontrolled wheelie at around 20kmh. Still recovering from the bruises, but very...
I chose 1.85", so that I can use the Tubliss system. They have around 10% weight penalty. I love the cornering on the Conti KKS10 (2.5")
The dual use Shinkos (2.75") were in my opinion horrible for cornering on the street.
I also ride in a very puncture rich area. Here my current findings:
going from bicycle to MC tires helped a bit, but not too much. The typical thing over here are nails, construction staples, screws and bolts.
If you want to be 100% puncture proof, you could try mousse in MC tires. Rolling...
My conversion has been taking longer than expected. First I fried a Cycle Analyst and bought a replacement. Then I decided to keep the dirt tire on the old wheel and built up a new wheel with new 5KW motor, including statoraid and hubsinks. The dropout needed to be increased to 150mm, hence I...
Thank you for the feedback. I didn't like the rolling resistance on the 244s, but am happy with the Continental KKS 10. Low rolling resistance and much better cornering on the road.
I buy the tubeless kits on Ebay. Just search for Tubliss. You need the full kit to start with for around 90 USD...
here my findings:
1) reducing the pressure made things worse. On top of the bouncing it induced some wobbling as well. Reduced range with reduced pressure
2) the bead was sitting perfectly
3) I bought some wheel weights and needed to add almost 6 ounces ! (ca. 150grams)
No more bouncing...
Oh that explains a lot. I should have known before. It was hard to fit almost 4" when you think you are getting 3.
I will check the bead once more, although I did already when mounting. That has been a common issue for as well.
Thx
here an update on my conversion to 19":
First of all the Excel Takasago 19" rims are way easier to true than the "porky" Chinese ones. I did a weight comparison as well:
26" MTB 1640 grams (with brake disk)
21" Motorcycle 5850 grams (no brake disk)
19" Moped 4650 grams (no brake disk)
here a...
So I installed a simple fairing yesterday and tested it today. My top speed, which had been hovering around 67kmh went up to 75.8 !!! All of that with a little piece of plastic...
Thank you for the explanation. I got my normal car registered in the Scottsdale DMV, so I know that location as well.
The e-car which I am building has a base kit from the UK. They have already sold around 100 of them in the US (with gas engines). None of their equipment has got a DOT...
