Would it be worth it, or would it help with efficiency if you had 3" tires or even any change at all?4" front and back. looks cool but i pay the price on efficiency!

Yes,,, Full Suspension is sure nice for us middle age folks H.P. ,,, the S-75 is not street legal,,, but they would never look into this in our area,,, its not as if i cant put a S-25 decal on it and ride every where...
We rarely do bike trails in our area since there are way too many gravel roads,,, secondary hwys and nill for people using them...
More roads then humans is a good thing...
As i mentioned,,, my friend with some pedalling issues can join in with us on some rides,,, i was planning on packing 1 of our 5 gas powered bikes on the winch tractor im running,,, it would be much easier doing an electric bike instead,,, i can charge the batteries off the Billy Big rig since they have built in Inverters too run house hold appliances ... pretty easy too charge a battery with the 10 too 16 hour runs...
Plus it will give our group of riders a chance to experience a off road gear drive hub system,,, if it pans out,,, we can do 2 of the 4 fat tire bikes we have...
2 units will get 2 smoke engine kits,,, the other 2 units will remain with pedals only unit we do a rear gear hub test...
Our local supplier on the West coast will look after all of our needs since they service and sell everything we need...
Good too start a quality relationship with them since they will be our electric power bikr handler...
They will deal with all the tech stuff,,, we will run the wheels off of them...
A win win...
Its unfortunate that our friend has a power crank set /// set back in life,,, but this option of non pedal power will allow him to join in with us on some of our outtings...
We are houner'ed and humbled too have him join in with us,,, a chance for those with """abilities""" too experience something of what we get to do in our lives...
Experience ones own freedoms of saying,,, """yes I can."""
Jt
Its all about friends and family in our world

i think it would. i do road biking and am riding at the gym to keep up. you be amaze at the efficiency of road bikes. 100-150W is about 15-16mph and 1000W is like 40+. these are like 20-23mm width or less than an inch and at high psi about 150~. and, weight at these efficiencies dont really matter as much.
imagine if my 3kWh battery with this efficiency, that is 3000/100 = 30 hours at 15mph = 450 miles. LUL . of course the ride is horrible, no suspension and high psi and a rigid frame while in semi aero tuck.

Ok,,, I took it apon my self too do some research on """the smallest""" % of this electric power pedal trike research I could find...
Lets call it the steeper grade hills packing some weigth,,, of course there are 1000's of variables if not 10's of thousand of conditions that can change the out come of how things play out...
What our group of riders is after is how steep a hill a unit can climb,,, how many lbs can it pack up the grade,,, % of efficiency,,, and how too lesson the electrical heat cycles on the motors...
Of course I will include mid drive in this for all of you that would like too go that route ...
Our group will be doing gear hub drive unit's for various reasons as posted above...
Lets get Wenche's awesome thread rocking,,, a way too find out what has changed...
Ok,,, the 2 links below were completed a few years ago,,, hard too believe how much has changed in the electrical power assist pedal bikes and trikes as far as technology goes...
Yesterday's achievements of electrical power pedal bikes are tommrow advancements...
Of course we could sit back and wait too see what comes next,,, our jump on board with whats out there now...
Hey !!! Each of us get too pick and choose what works for us,,, we get too decide how it plays out...
These 2 research tests went down a few years ago,,, yes that there are some variables,,, nothing is written in stone,,, and our own riding habitats could change the way things play out...
At least these articles offer 1's perspective of what he found out in his own test runs... And we get too reap the reward of his hard work...
Ill guarantee that I't will leave more questions than answers once a person gets done reading these 2 short articles... Ha
Heres his link too mid drive... again,,, the authors interpretation only... not written in stone...
Recumbent Trike Information http://www.triketech.com/Drivetrain/PowerAssist/MidDrive.html
This is the Gear Hub link article,,, only his prospective with variables attached...
Recumbent Trike Information http://www.triketech.com/Drivetrain/PowerAssist/HPV-MAC-V2.html
At least we get a idea on the steepness of the grade and how well some of these units did packing weight up the hills...
I think its a great way too find out how beefy someone of those motors are,,, and how much energy is needed too pull off those climbs,,, at least we have some number too work with...

@bakaneko Oh hey, is this normal?
When i WOT the ebike it shoots up to 1470 something Watts, i get up to the speed i want, usually around 25mph or less.
Then i just drop it down to around 100-300 watts varying with the terrain.
Just wondering if that is normal or if ima experiencing something bad about to happen

without knowing the specs of your motor, this seems normal to me. #1 that 1500W is your peak power surge to get up to speed (max RPM) and then #2 your max RPM must be translated to 20mph? for your setup so watts going in are matching the max RPM of your motor.

Seems to work alright so far
I cut a forked stick to use along with my kickstand so the wind don't blow the bike over anymore

Am I the only one who thinks this kit is at a crazy high price for an anemic weak motor? sure it comes with a batter but still. 1650-1950 canada dollars. Im sure a guy (or girl) could piece one together with better performance for nearly 1000 less. Or is Canadough not really worth that much and that is a fair price?
