'98 Quintana Roo panamint mxus xf07 350w fr hub

Post by eCue » Nov 22, 2017 12:06 pm

As parts roll in I have started to assemble the ebike
Had the panamint frame shipped to Canada from Mexico City years ago as a new old stock frame its still in minty condition without marks chips or paint flaws despite being 19 years old.

Image

Image

The frame is a 21 inch mtb frame = 3.6lbs
Manitou Scrarab Elite fork = 3.1 lbs
Front wheel with Mxus 350w Hub = 8.3lbs
Nexus 4-sp internally geared hub = 3 lbs
xt and xtr with ritchey bars stem headset
carbon bar ends

Started the thread to share photos / videos of my lightish weight ebike build then ride performance.

The Motor a mxus xf07 2.8kg geared hub motor is reported to have 60nm of torque and can make 1hp / 750w at higher voltages.

Image
The stickers say 26" 350w and 36v.which is odd as normally the 48v version is 350w

Image

If you have something similar feel free to add photos or links of your ebike / part choices and educate us.

Will add more photos when further parts arrive and the build starts to progress. Currently the rear wheel is being laced and its getting close to completion

Still waiting for the battery pas sensor and various switches to arrive

Performance gain

Will be adding on a set of mid 90's old stock Rito aerobar clip ons to the handlebars to reduce drag at speed.




I found out they do make a 36v 350w version they call it the upgraded version on ebikebc with a 350w nominal 550w max rating.Makes me think i'll get 450w out of it @48v.

Rated for 60nm torque at 36v , the inside of the upgraded xf07 looks pretty bad ass

I normally use Clinchers but bought a set 2.00 tires for the ebuild.
After checking the numbers using this http://bikecalculator.com/examples.html cycle calculator I will be using a set of Clinchers on the ebike.

Using the calculator it shows that I would gain 5 kmh for top speed and arrive about 25% sooner. Not sure how to convert it to ebike battery distances as a lot of real life factors come into play.

Image

I guesstimate the tires and aerobars will increase distance by about 35% optimistically using clip on aerobars with a set of clinchers.

My current ride with 1.25 slicks on

Hard to tell from the pics. Is this a front or rear hub motor?
oops ... guess I should have looked at the title.
Did you ever get this finished ?
The more I learn the more obvious the immensity of my ignorance becomes.

Yeah thats just my pedal bike
Still waiting for a slow boat from China shipping the battery also I re-ordered a little KT controller rated for 36v 20A or 48v 22A 350-500w.
Hoping to have it on the road by early January.

Side note decided to nix the clincher idea and use some low rr 2.00 tires for their added safety and versatility.

You might find this story interesting ...

Unless you go for sewup, I think you find nearly all current bicycles are clinchers ... I could be wrong (that happened at least once before).

That was informative , Amazing how well the Specialized S-works Turbo tire did vs the Tubular tires pretty much neck and neck with 31.6 vs 32.8 rr vs 53 and 59 of the bottom contenders. It seems Specialized has some kind of Flubber rubber ! ..
side note Clinchers relate to the tires thin profile to be in the mix you must "look" the part
