E-S Phasor Electric Bike Owners

[Rix]

Paule, to get the Phasor frame, if it costs about 1900 here in the US, what would it cost after going through German Customs? I am familiar with Foes Racing from the early 90s that Foes was the grandfather to all long travel DH suspension bikes. Even though long travel back then was classified as anything over 4.5 inches. Hell, I remember when everything with 3 or more inches was big. There were a couple of other 80s bikes that preceded Foes but Foes was the first long travel to work decent with pedals. I would rate Mountaincycles San Andreas second during that era though even though it was a little older then. My opinion, doesn't mean I'm right. I think the phasor frame is an awesome option. I am sure It wont' pedal nearly as efficiently as a DH bike with the same amount of travel. It wasn't meant to though. It was meant to do what Rodney and HD Killer did with theirs, which was to be an elctric bike with DH Geometry that could house the battery in centralized mass location. BTW, I pedal my bomber under human power only for work out purposes. It not efficient either, except at burning calories. Anyway what ever direction you go, I hope you post pics of your prospective ride. 8)

my first FOES was a "weasel" from 1996 and I remember the san andreas... if you cut that frame in two half you can use it to store batteries too

pictures I will post as soon as I know which direction to go...

In the beginning my prefered build was the rocha mountain drive as mid motor, in combination with the rohloff gear hub this would be a climbing monster... if there wasnt that noise of Astro motors.

I like the "silence" of a hubmotor, if the hubmotor is able to climb steep hills... the last days I tried CAD "cardboard aided design" to create a batterie housing around the dh frame but i think this will not work..

maybe I can use the battery in a backpack like the EGOkit from austria does... since I am allways using a backpack on singletrail tours, I "simply" have to add the battery in the backpack, the controller at the frame and a hubmotor in the rear...

sounds easy, but I am not sure...

Dh-Paule,

Carrying power on your back riding two wheels is something I know about. Growing up riding MX bikes in enduro type settings and being too cheap to buy a desert tank, I carried a gallon and 2 quarts on my back for years. I got used to it and rode that way all of the time. It wasn't until 1992 when I entered the Emmet New Years day snow race that I realized how nice it was with no gas pack on the back. It was a short 31 mile race and I had the range to go with out a gas stop or carrying. After that day, I started crapping greens for bigger desert tanks on every bike I rode. I also rode with a 1.6 gallon Acerbis tank with chainsaw rack mounted on the forks as well. That wasn't bad at all, just a little slow steering in technical rocky terrain. Some guys have converted HD bike with custom lipo racks mounted on the front fork tubes. I think that would be a great option also. Topfuel just finished with a really nice and clean ebike conversion running a Crystalyte H40XX series motor with custom fab dropouts and Lifepo4 battery mounted to the fork. Its a really clean and nice ride he put together. Here is the title of Topfuels thread on the forum. I don't know how to post links but he is from GB and this is his link. "New Build crystalyte 4080 / 3580 down hill bike UK". Out of respect for the Phasor builders, I am trying to keep the topics and comments here specific to the Phasor. Sometimes I branch off a little far on Stealth Bomber tangent but I am trying not to do it too much. I do the same on the Stealth. I would like you to check out Top fuels build, it may give some good ideas. Let me know what you think about his build.

That looks excellent!

thanks! put some heavy gauge spokes on back ...couple more days be ready will see how it goes HPC did nice job on wiring neat clean hopefully it performs as well as it looks...4500 watts with venting should be nice will up to 5000 watts later maybe double battery too!

Very Nice! Couple of quick questions......What rims did you end up using for the build? Your seatpost is up quite high, how tall are you?
Looking forward to hearing your first riding impressions.

alex rim on back with 10 gauge spokes...honestly do not remember front rim....the seat post has not been cut yet...few other areas need fixxing too...this is not the final configuration but just to get me riding want to incease voltage a bit and battery capacity too waiting for new components

 

[Rodney64]

Guys, it's been a steep learning curve for me I'm going to go slowly
Now.

Most of my posts I learnt the hard way. If I can help with your build I will. I'm limited to the components that I've used but maybe able to help.

Hey Korp,

Your Phasor is coming together nicely. Glad HPC is came through for you. An air shock on the rear? How much do you weigh? If you find yourself needing to put more than 265PSI in the hi comp chamber to get the ride you want, consider goint to a coil over shock @ 9.5- 10" long from eye to eye. Keep in mind that the longer your shock, more ground clearence you get, and steeper your head angle will be. I can't remember what the shock compression/swingarm travel ratio is, but if its north or 2.7 to 1, you will be working the crap out of the shock if you are heavy like me (230+#). If you are only riding on roads, forget everything I just said, the air shock will be fine unless you are 300# masher. How are you getting the 4.5 KW? (90 volts 50Ah? That 4065 with the 26" rim is a good match. 80Ibs, thats just awesome. What kind of battery you got? Can't tell for sure, but it looks like you didn't dish your rim, that means its much stronger Keep the pics coming, and please post a ride report after you take it out.

hey rodney! did you have to cut a slit on your seat post?...mine does not have one and the seat cannot fully tighten!

well if I remember reading correctly,the shock has some type of device that accounts for heat when the ride gets bumpy to keep the shock travel and performance from fading...I had the same concern about having no coil but they say its not needed and it saves some weight...i weigh 180 butt naked..not sure on this battery since its only temporary untill we get 100 volt system going at 50 amps only 10 amp hours now will fill you guys in as i get it up and running and take more close ups of details the newer batteries will be lithium nickle or something like that close to weight of regular lithium but more cycles 1000 instead of 700 and lighter than lithium iron

100 volts at 50 amp will make your HPC65 scream with power and torque, and since HPC vented the hub, you will be fine. Just monitor your heat when climbing and/or going slow under load. I am betting that your shock is more than fine for 180#. My Fox Air on my Specialized was fine for me at 260# 29Ibs for the bike. Just had to pump up the pressure alot to 260-265PSI. I don't think It would have been fine for me and a 80# bike though. Sounds like the HPC guys taking care of your needs. Tell me the brand and model of your shock, I am curious about it. I haven't farted around with airshocks for two years and they may have changed immensely since then. So my information could be dated. Important thing is you are just about up and riding.

think it is Roxx shoxx vivid air or something like that....it has a plastic piece inside that extends when it gets hot to keep air levels even and shock performance from fading on many successive bumps...HPC put heat sensors on motor and automatic power reduction when/if it gets too hot I requested it think it annoyed them somewhat but think its worth it so a newbie like me does'nt fry his motor on his first day out

 

[litespeed]

The heat sensor is a really cool idea. Can't wait to hear how it all works together.

some photos

 

[dimpirate]

Looks really good korbin!!!
Do you guys have to take covers of every time to charge, balance or is there some sort of opening for that?

no they gave me a quick disconnect for charging velcros to back of bike will include photo shortly

 

[korpin]

after charge and a few trips around HPC's parking lot showing 100 volts

 

[Rodney64]

Korpin. I think did the right thing having HPC doing all your electrical work. The bike looks good and it will be worth the wait.

A couple of thing I've learnt with lipo as I was new to it when I had my battery made for the Phasor

1. Im always are close by when charging. I've been setting the timer on the oven for 50 minutes to remind me that the battery's close to charged.

2. Regularly checking the pa me are balanced.

3. Not charging over 4.1 (this is a 100 volt on my battery)
4. Never running the pack below 3.5( ill turn the bike off a d pedal rather than ride it) this is 85-86 volt.
5. A d it you remove the pack from the bike new put the battery down on a surface that isn't clean as it may damage the pack. Any damage which punches a cell puts the pack in risk if being out of Balance or worse fire.

 

[Rodney64]

hey rodney! did you have to cut a slit on your seat post?...mine does not have one and the seat cannot fully tighten!

Korpin just noticed this post. Yes I cut the top this was the only way I could get the seat tight. I think I posted a photo previously. I will repost it when I get home.

Korpin still having trouble with your seat post.

The below photo shows the cut I made so I could get the seat post tight

 

[korpin]

well final photo of my baby by bed.....one of the goals of this project was to get stealth bomber like power and range and suspension but in a fighter like weight I think HPC may have come close not sure yet will ride this weekend but glad right now its 36 pounds lighter than the bomber

I live in an apartment and my garage is subterreanian so that is two flights of stairs to haul up after working all morning underwater in a swimming pool that was freezing at this time of year

would like to make it lighter the only thing I can think of without sacrificing power or range is the new aluminum stator motors coming out that would be 2-3 pounds cannot think of anything else but a whole new frame???? thats one of the advantages of the geared drives LOTS of weight saved! (I do not meaned geared hubs but the geared drives like the audi bike)

 

[Rodney64]

Korpin good to we that you have her home.

Keep the photos comming. I recon with that long wheel base you'll be able to ride the stairs.
