someone consider offering

bbsxx controller rebuild service


gotta be many 02 03 cores

22 miles on 840wh if thats what actually have seems about right to me obviously last portion lower voltage if capacity further degrades perhaps attempt balancing leave on charger several days disconnect and reconnect several times post final resting pack voltage amazon 28ah pack comes with bms life ...

if jumping correctly

no pas or throttle action

inclined towards duff controller

or perhaps internal wiring

check moisture ingress

3 dollar chain wear gauge replace 10 15 dollar chain any measurable wear sprockets will last very long time my chain interval about 1000 miles large hubs using bicycle rims will not lace strong durable wheels even best spokes and lace job eventually fail heavy commuter experience something gotta giv...

recheck all connections


correctly bypass display

jumpstart motor controller

works under throttle

or top pas level

may help

rule in out display


test health of battery pack

not only voltage

current under load

10000 miles cute

nothing wrong learning from others

however doing final proof



bbshd do not shred hardtails in six months

utter nonsense

apparently offered by think not facts



good luck op

some only think

others actually do

the later know

extensively used every extreme

span quality full - rigid

low pressure fat tire favorite

roughly 25mph performance envelope

all terrain performance

good comfort less complicated

excellent choice for bbshd

butterfly bars

flex but i want that

lotsa room for attachments

don't thank me

responding to op

but yeah eyes of beholder

no color splash screen

horizontal only

but it works and works

keeps delivering for

many systems similar to op and beyond

use cycle analyst ca

china displays fw weird

ca configures

manage everything to ride

charge each parallel group

as single lipo cell to 4.20v

bbs01 02 began 250w 350w 02 rating magically grew to 500w 750w 900w 1200w peaks reality 500w 600w continuous cool temps hand or temp sensor will not react quickly enough be mindful continuous power can be very dependable sans water of course front tire will spray water directly inside older 02 throu...

riding too fast eventually suffers

slowing down rarely does

look but never stare fixate

constantly scan using all senses

be aware of everything

assume worst

plan for best

ride long and prosper

mid drive for this job

12ga should be fine

for that application

man above spot on

applied things in ev world

learn important concepts

peak average nominal

voltage always changing

under various loads

similar variation power usage

enjoy

consider em battle tested

no blogs no posts owned 4qty bbs02 burned couple controllers like you thot all good best understand duty cycles surviving 850w continuous depends on several factors ambient temp rpm load 600 700w will likely climb most anything slowly using low enough gearing bbshd survives 1000w continuous although...

1200w yes short term

it is a 600 700w continuous system

understand continuous vs peak

temp sensor wont react quickly enough

good luck

nice job

fyi

bbs02 is not 1000w system

for cool temp days

600 700w continuous max

will survive brief 1000w bursts

enjoy

even with superhuman power levels

sprockets dont wear much

using good fresh chain

using worn stretched chain

sprockets turn to shit

quickly

depending on programming lower pas levels limit peak power levels display with power meter can help visually depends on bike in general much smaller than 40t little if any offset results poor chain line important thing regarding 1000 1500w pulling chain never run worn chain any signs of chain wear s...
