I am just starting my new build, a 200kw peak monster.

specs:

battery 108ah 104v 1800amps peak, 900 continuous

controllers: 2x 1082400 Ev surin fardrivers 1700 line amps each, 2400 phase.

motor: modified qs268 100h magnets, wound for 180mph, hoping for 160mph trap speed on the track.

frame: ice bear mad dog, Will probably require some major fabrication to fit the battery and some major reinforcement across the entire chassis, but it's the chassis I've chosen and it has a VIN number so that's nice.

Right now mostly just waiting on the swing arm and brake rotors and calipers

The goal for this build is it's just a really stupid powerful build that's really as simple as it is. it's something I can throw a sticky tire on and take to the drag strip, or ride it around the neighborhood and get groceries.

hopefully on the road to 250hp on the strip.

it's been awhile since I posted on here, my last time posting was my first time ever building a bike and now I'm probably about 7 builds deep, this project is my baby though it's very much the razor of Theseus.

specs:

96v 38ah battery, 400amp peak 280 continuous

qs260 70h

fardriver nd961000

frame is / was a razor frame, extended about 7 inches in length for the larger battery, with some body panels I formed up in a weekend to hide the wires and give the bike a more complete look

still need to pull it apart and get it powder coated but I'm very happy with the bike and ride it frequently.

recently finished my minibike and the chain makes this HORRIBLE sound but only on decel. i was careful to make sure everything was aligned, it sounds fine at any speed so long as im actively on the throttle, if i am coasting or actively braking it makes a sound akin to a broken blender. second pic is a better pic of the chain run. anyone else with a similar build run into the same issue? fixes? lmk. brakes also are for shit, brand new everything and it squeals like a stuck pig while not having much braking force. maybe the bike is just too heavy for stock mechanical brakes now?

Looking to replace the handlebars, i want some pro taper bars but not sure what size I need.

will this 72v kit fit inside my 135mm dropouts if i stretch the rear forks to 150mm. thanks
specs of kit : 5kw
current spec on bike, 135mm 2kw 52v hub and 72v 20ah battery
