Re: is there any HIGH quality throttle ?

not exactly high quality but cheap and mine has working great so far! I run this with my normal robust motorbike cable operated throttle

Re: Votol EM-100 & EM-150 controllers

When you guys have a cut out do you also have to come to a stop before and then pull away again to make the motor turn?

Re: Big wheel vs Small wheel scooters - saftey

I have a monkey bike with 8" rims which rides fine even geared up to 75mph, but hitting a pot hole with smaller wheels can be brutal

Re: Why are two speed transmissions not more prevalent?

I'm also very curious about the use of a gearbox but in my mind it makes more sense to just use a larger motor if more top speed is required, that way it is simpler/less to go wrong, less losses from the gearbox and potentially less weight.

but would love to hear pros and cons to both set ups

Re: Votol EM-100 & EM-150 controllers

Why is phase shift at 45? It’s 60 for me with the qs motor and i think that’s the correct value. A large FW is the same as phase shift add on, you will get closer to 60 due to this. If angle is not correct then this will affect all your tests Not sure if it makes a difference with the 2000w motor a...

Re: Votol EM-100 & EM-150 controllers

Hey Zeronest, thanks for sharing. I wonder if you have the same sw version (despite the fact it's em100). Regarding the decel lag you're describing, try to set both rate of rise and rate of decline to 255 (page1). There's a noticeable difference in motor response, but still not what we're after. Mi...

Re: Votol EM-100 & EM-150 controllers

I am using votol em100 with qs 200w motor in small motocross bike and am also having some power cut outs, often when I am applying a lot of throttle but the wheel cannot spin ( if the wheel can spin It doesn't seem to cut ) I lowered the undervoltage value and it seems to have helped but I have stil...

I'm looking at the isdt q8, it seems it'll serve me well. Any reason you put the psu's in series?
The charger will charge with 12v input but it will only supply 15A of charge current, if you want the full 30A output it needs at minimum 24v input

Re: Motor for fast e-bike

The QS 3000w mid motor kit is really powerful. If you want to go 50-60 km/h then it’s too large, also to fit it on a bike won’t be easy. Motor alone weighs 10kg and fits on a motorbike The QS 1000w or 2000w mid motor kit will be better for the job and would be what i would choose before the other t...

That's coming along great!, you definitely need some footpegs!

I used to use an old large innertube cut open for rubber to use as a rear mud guard to protect the shock

Re: another pit bike conversion

Had a couple more test rides on this bike now, upped the controller amps to 150 and then realised how completely absurd this motor is for this tiny bike! now dropped it back to 100A and tempted to go further but its so much fun! Received this throttle, And it works great! much better response than t...

@larsb Which manual are you reading from? I've been using the 2000w motor with em100 controller a little bit now but cannot seem to make the throttle response sharper in controller settings, is this just the nature of a low kv motor without reduction drive? I have switched off soft start which helpe...

Nice build! :thumb: Maybe get a 12" rear and a 14" front wheel combo in that bike if it would fit? Thanks bud! Yeah 12/14 would be far far more suited for this motor although probably still complete overkill, And I am very tempted to build up another chassis in the near future but 10" wheels are su...

Re: CRF250 Build

sounds like a great bike to convert to me, the crf150 is a steel frame but a smaller bike too, in terms of frame weight though there really isn't a massive difference between and aluminium and steel frame if that's why you're thinking aluminium..
