Hi all I have a d2 the peddles assist is very slow like 5kph is there a way too make it faster Like unlock the peddle assist Or Would it be a faulty sensor Thanks

Hi all my d2 battery light flashes 6 times on the display but the bike seems fine getting speeds up too 28kph any ideas please

Problem solved Thanks everyone for the help I'll do my best too help others

I think I might found the problem, it seems too knock off when the bike is been moved or bumped, I think I have a loose wire in the display when I turn the handle bars it powers off and also its the only connector other then the power supple that if you disconnect and connect back together you need too power the bike back on wish me luck

I feel like I should make a new post it's bad manners hijacking someone else post, So the bike is fully charged 42v and showing full battery on the clock, I double checked all the wiring made sure everything is connected correctly and tight, When I turn on the bike it could knock off in a couple of seconds or stay on for 10 to 15 minutes Any ideas Thanks

A lock will only keep an honest man from taken your bike you want too slow the person from taking your bike so lock each wheel induvial and then lock the frame, most theft is opportunistic

Thanks for the reply its a new battery I've checked the wiring and all seems fine

Thank you very much It works now however it randomly turns off when I am using the bike, any ideas

The P1 is wrong it's showing P1 is 48 P2 is 200 P3 is 29 When I try change p1 too 36 it won't save Also what are the p2 and p3 ment too be set at Thanks

Your throttle is broken Ignition is just power on and off You have 3 wires that are ment too be connected too a sensor, without that sensor your bike will not drive,

I bought a new battery and when I plug it in too my sons D4s its showing lower power 1 bar of power When I plug it in my d4s it's a full battery Any ideas

Look up my post from about 2 weeks ago I posted the wiring for the D1, D2 and the D3

Dublin Ireland

Did you have any joy on your battery, I have a similar problem on charge all day and only getting 31v

11 pin the ground wire is the last pin on the right

Yeah so when I have it on charge it will only charge too 31v it should be 42v I have the battery opened up and have access to the BMS what should I do, Will I try charge the individual cells on there own

My battery stops charging at 31 volts has anyone restored a battery did you do it successfully, Also plan B were is the best place to buy a battery I'm located in Ireland

Hello From Ireland

Hi all I made a list of what wires go where

Hai risolto questo?

Hi I have a D2 and I have no power too the motor lights/horn/usb and the speedo I want too inspect the hall sensor and the wire's are broken off so Question can the sensor be bypassed Do I buy a sensor and solder one in OR buy a new throttle from Fiido little bit of history on the bike when I got the bike it was the wires where all disconnected from the control box (Don't know why) with my multi meter and this post I manage too get things working https://www.pedelecs.co.uk/forum/threads/fiido-d2-wiring-diagram.35598/post-528923
