Sur Ron with: Loom and Voltmeter
Set for bike with a STD 60v Sur Ron battery and Battery Bypass
Higher Volts, Higher Amps Higher RPM+ Higher Speed !
More acceleration and more top end.
Delivery time is now up to three weeks if showing on back order, in stock three days, as we deal with demand. – Thank you
Set for bike with a standard 60v Sur Ron battery with the Battery Bypass mod ( we offer the mod in the batteries section). This will be too powerful for a standard un modified battery and a little pointless to spend this much money on a bike with a standard battery!
We wanted to bring a slightly cheaper but more robust version of the controller with no stupid gadgets and updates. This version simply bolts to the bike and uses the existing throttle. Add the handlebar ebike built volt meter, to tell you your battery state and your ready to go. Expect a shock as the 7000 watts to kicks in!!!
We figure when you buy a motocross bike, you dont sit there looking at a speedo, most don’t even have a rev counter (why do you need this on an electric bike?) You dont turn your power down just because your running out of fuel on a gas bike, you just go gentle on the throttle – same here! If you want to know your speed then stick a bicycle GPS on the handle bar or strap your smart phone to it (you can let your little sister or mum call you too), but when you want to go fast in the woods, with nothing to break and no updates or silly flashing colour screens, take the phone away and you ready to race.
I ride my bike like this but with a bigger rear cog 56T and I’m 20 stone, I still have to lean forward to stop the wheel coming up!!
We highly recommend changing the rear cog to 54T or 56 T, 60 T is mental to 40+mph and experience the blistering improvement in acceleration. This reduces strain on the battery and increase the range but you will lose a bit of top speed. But the bike will still hit 45mph top end (or more) but becomes a real trail power woods bike.
Set at the same power as its slightly smaller brother the 4000, but it doesn’t choke the power back because of heat . This controller is designed for much higher power outputs than the 4000. The 8000 here finds these power setting extremely easy to handle and with much better cooling. The 8000 is able to convert more DC amps to phase amps than any other ASI controller. We make the same profit by selling either controller, but just cant see the point of the slower 4000 on this race set up, but in our opinion the sheer superiority of the 8000 makes buying the 4000 crazy except for a small saving.
Power sets from
7000 with upgrade with standard but bypass modded 60v standard battery (we feel this is the limit for the bypass mod)
Controller Feature Set
- FOC (Field Oriented Control)
- improved torque throughout the rev range
- Higher RPM compared to the stock controller on 60V and especially on 72V
- Silky smooth throttle control and responsiveness.
- Improved efficiency due to FOC algorithm, premium internal components within the controller (like the mosfets) which increases efficiency while reducing heat losses
- Automatic sensored to sensorless transition which gives you addition 5% top speed and better performance
- Usable voltage is 60V nom (48v – 67V
- Mounting Kit
- Install Instructions
- Volt meter
we recently after a long relationship broke away from a well known Californian business who supplied us these controllers. We found the latest display supplied by them was simply to difficult for most users with features that caused too many issues.
Now: no updates, no messing and no home made display cases.
Unfortunately this set up will not allow the simple swapping of battery voltages. You have to choose your battery voltage and stick with it. We will however change this voltage for you free one time only by appointment via remote session on your laptop with a Bafang programming lead. So if you buy the controller to run on a 72v battery and then for whatever reason go back to the 60V Sur Ron power battery, the motor will still work
The handlebar voltmeter will show full at 67v , half way at 60v and motor stop at 48v. So at 53v under load start nursing the throttle. Remember its the displayed voltage when your under power, is the voltage that counts, not sitting in the paddock or down the pub
Sorry but we will not be supplying any Bluetooth codes.
This set up is too much for a standard battery without the “Bypass Mod”
