Sorry didn’t see this before - if I remember correctly the button/icon on the top right (looks like a head with speech bubble) switched between languages and enabled me to put the parameter labels into English.

I sold the Quazzar last year with the original controller and 60v battery as I decided to do my full bike test and needed a 125cc to get through the Mod 1/2 tests. I had my 72v battery pack built by a UK guy (Mersebikes) - he’s on Facebook and you can find him via Google. I know he was having...

SOLD Enduro EEB frame with Moto style seat, Crystalyte TC3080 laced into red 24”stars rims, 12 FET / 40A controller (all purchased from EM3EV). Programming cable and software for controller. Rockshox rear shock. Zoom upside down front forks. Battery meter and GPS Speedo fitted. UK built 72v...

SOLD Hardly used Cycle Analyst V3 - came off a project Enduro eBike build which never really got used. Will be placing separate listing for the Enduro EEB bike frame, wheels, Crystalyte hub motor and controller, front/rear shocks and 72v 20ah Samsung based battery pack later. Excellent...

I’ve been there with the same topic - lots of folks have previously tried to change engine class of a 125 to 50cc to use it on a moped licence and DVLA are wise to this. I even looked into doing something similar with a wrecked Zero FX and downgrading motor but DVLA wanted a formal engineers...

Yes I would definitely use the Yamasaki frame again given low cost of donor bike and the fact it is almost a 600cc large size bike which comes with a lot of space inside the frame for battery box, and under the tank where I mounted the controller. It’s not a Yamaha or Kawasaki so you need to...

Sorry forgot to say …. Factoring in battery pack, motor/controller and all the other bits such as contactor, display if you want to monitor battery in real time, cables, crimping tools etc you are looking at £2,500 - £3,000 on top of your donor bike …. based on my experience when I built mine.

I’m the guy who built the Yamasaki - what I can say about the 4kw hub motor I used is that it’s definitely equivalent of a 125cc using the 72v pack I had built. Acceleration is quicker up to about 25-30mph than a petrol equivalent then it’s about equal and tbh it tails off after 50mph. All on a...

Been a while since I posted an update on the Electric Yamasaki - various lockdowns in the UK have meant time out on the road over the past year has been a bit limited but the miles are starting to build up now. Only issue has been with the the indicators which was a simple fix and just needed...

Just sent you PM with some links to UK suppliers of batteries for these types of scoters - note that some Artisan type Vespa clones run at 72v. As you will see from previous posts on this thread it is possible to configure the Quazzar controller to run at 72v but as you will have seen from my...

Update on the 72v pack - it didn’t really make a difference to top end speed. Slightly quicker acceleration off the mark. So I think this just shows the controller is limiting phase amps to the motor.

Just replied to your message

I used a paddock stand with the hub motor axle clamped to the swing arm supports to do the initial testing of my motor, controller battery setup. It was OK for low speed / low RPM testing but be careful with putting too much speed through the motor as mine tried to pull itself off the clamps...

I managed to have a play with updating the controller settings - all still on the 60V pack as I’ve only just got the connectors come through the post to be able to connect my 72V pack. First off the app itself isn’t that intuitive - took me a while to work out you use the upload function to...

Haven’t had time today to update controller settings but I did get to take the second controller apart. It’s definitely a 72v controller with 100v caps so shouldn’t be any issues running at higher voltage. It’s a 12 FET controller and looks to be a straight UGBest rebrand of the LBMC72122 -...
