    1979 Honda Electric Dream (CB250N conversion)

    Well... that was a really long month! *Bumping the thread so that I get back to working on it* It turns out that moving a few hundred miles away and leaving the bike in storage isn't a good way to be productive :roll: Let's see if I can get the motor mounted by Christmas! Also, I need to...

    1979 Honda Electric Dream (CB250N conversion)

    I did very little on it over winter, the project is still going - just slowly. I've been working on finishing an MXUS based bicycle project first. Hopefully in a month I should be back to the motorbike full time.

    BobCs emax scooter thread

    Hi Bob, Any chance you could share some details on the laser cut battery plate parts? What did you get for your £20 and did you supply the material or was that included? I'm looking at swapping out my hand cut motor mount with something more accurate (and a bit nicer looking)

    New Electric Belt Driven Honda Grom/MSX clones

    Welcome to the forum :) As far as your modification plans go: (this likely sounds a litte critical, sorry) The battery (72V 40Ah?) would be delivering 16A (0.4C) in the original bike, moving to the motor you suggested would require upto 320A! (8C) to make the bike for $1000 they almost...

    1979 Honda Electric Dream (CB250N conversion)

    It's actually pretty close... based on typical levels of chain sag, It may* very occasionally touch the top of the swingarm pivot with the current positioning of the motor, to increase the clearance (move the motor up) I'd have to move it further froward which I'd rather not do. The engine's...

    Radial Cooling of RC Outrunner

    Looks good :) I'm interested :D Are you filtering the air in anyway or are the baffles you mentioned there to help prevent things getting drawn in? Also how much power does the fan draw (I didn't spot power consumption on the spec sheet)

    1979 Honda Electric Dream (CB250N conversion)

    Thanks Sparta, the stepped key is interesting, I'd not thought to look for that, sadly uncommon outside of the USA. I've had a look at the taper bush specs: the bush without key can do 51 N.m The motor with torque constant 0.12N.m/A would need 420A to get the sprocket to slip so for initial...

    1979 Honda Electric Dream (CB250N conversion)

    Yes, ordered on the 26th. I'm not sure how long it takes them to make them - they start from blanks so I'm hoping to see it some time early next week. My budget isn't really defined... but I figure that a good DC-DC converters will last and I can use it in anything else I build. I think so...

    1979 Honda Electric Dream (CB250N conversion)

    Transmission/gearing I hadn't even considered a jackshaft! I've got a 70T sprocket on order so I’ll see if/how well it fits with a single stage reduction before I look into the details for adding a jackshaft. The axis of the front sprocket isn't too far out from the original position and the...

    DIY handlebar display

    That is sort of what I was planning. As I don't need an oil pressure light/neutral light I was thinking of squeezing the display in there. I'll have speed from the origional speedo and might see if I can modify the tachometer to display current, which leaves voltage/temp/cell status for the...

    DIY handlebar display

    Great to see that you've posted up info this, I love how compact you've managed to get it. :D I've used these little OLED displays for a few things attached to rasperry pis, and have been thinking about using a couple to show voltage/current/temp on the dash of my motorbike project, I'll need...

    Drivetrain design time This is in part written so people can see what i'm thinking (so if there are mistakes they don't have to make them in the future) and partially for my own future reference. To calculate the power needed to move the bike I have been putting some parameters into the...

    1979 Honda Electric Dream (CB250N conversion)

    The motor has arrived and I am now working out where it will go and how the mounting plates will fit in. A very rough mock-up is shown below: (Purely to see how it MIGHT look) The current thinking is to use some fairly thick 10-15mm aluminium plates extending from the front engine mount to...

    1979 Honda Electric Dream (CB250N conversion)

    Currently at the top of the list of possible motor options is a Motenergy ME1012 Edit: I just purchaced a Motenergy ME1012 (I found one in the UK, which was about £300/$400 less than importing one!! :D) The ME1012 is mentioned very little on ES so I've been looking for the differences between...

    1979 Honda Electric Dream (CB250N conversion)

    I am tempted by the QS hub motor but it would mean that I lose the comstar wheel (which lots of people like the look of) and also means that I would need to fabricate some kind of disk brake mount for the swing arm, which i'm not keen on doing I'm struggling to find out how much it costs in...

    1979 Honda Electric Dream (CB250N conversion)

    Hello All, I've been thinking about doing an electric vehicle conversion for a few years now and have now actually started! The overall goals are to: Get road legal Speed - Not hold traffic up too much. Range - Initially 5-10 miles (50 would be nice but batteries are expensive!) So a...

    Buying used brushed motors

    Hi, I'm not sure how but I've managed to spend 3 years on here without posting a thing! (And have been reading stuff for around 5 years) I'm finally getting ready to start on a small electric motorcycle conversion. I've found a couple of used AGNI 95Rs for sale If people have asked this...
