Minivans ARE faster than Miatas, which are still the best selling convertible of all time.

There is such a thing as the joy of driving a slow car fast but it seems to be lost on most Americans.

A sportscar is about so much more than 0-60.

An enduro-x track would have made way more sense then rolling the jumps on a moto-x track.

Adding even more weight to the rear wheel in the form of liquid cooling would have very limited application as opposed to simply building a better architecture where the motor in in the middle of the vehicle.

The first company to engineer a rear engined kit car that accepts a Leaf donor will be onto something. Like the Factory Five 818:

Half the weight, none of the traction issues plus a tuned controller could make for a pile of fun.

Put me down for zero detent, low breakout forces but progressive force increase away from zero along with an exponential output if possible.

Look at large format EV cells and expect limited lifespan.

If you were willing to accept duty cycle limitations plus lifespan reduction I'm fairly sure most EVs could produce twice the power. At least the ones which aren't already sold as performance cars. Most EV cells are only charging to 4.05v and limiting discharge in order to hit longevity goals. That ...

What part of VI are you on? I commute 4-5 days a week in Victoria on a DIY ebike.

This may only be a percent or two more efficient comparing peak to peak with current technology, but the potential for it to extended the efficiency plateau significantly in both directions is something that will need to be considered. Flux weakening increases RPM but with a fairly significant torqu...

20kw puts it in the 125 class if they can keep the weight down.

I'll be watching your progress on the faster models. I think there is a lot of room in the market for lightweight electric motorcycles which don't cost a huge amount.

The only thing I'd point out is that there are a few 150mm hubs which have a 6 bolt brake mount on both sides. Oh thats good to know! I saw a few out there but I couldn't seem to find one that was readily available. The wheels are already built but if things need to change that's good information. ...

It's steel? Yeah that'll add up for sure.

Thinking under 250lbs?

I'm thinking less about EV conversions into ICE vehicles which will also likely involve taking the best/cheapest components regardless of original manufacturer and combining them. What I'm thinking is reflashing to allow higher power than can be sustained for use in limited duration motorsport such ...

Any worries about getting the motor to work without the CANBUSS BMS?

46kg is quite good. What battery size would that include? 18650 48v57.6ah 156*3200 5C-10C My priority is low power. The high-power ones are simply tested. The battery box is too large. I have to make him beautiful. :lol: 48v seems very low to allow good speed using just one gear. Have you thought a...

46kg is quite good. What battery size would that include?

It'll be reflashes, body modification and suspension tuning.

I highly doubt that motor or controller swaps will be very common. Possibly range boosting additional batteries.

How much peak power are you thinking? Estimated weight?

I was considering the same motor into a youth sized frame (KX100/105SX/CRF150RB).

Estimated weight for a model that peaks at 10-15kw?

I personally don't like the battery crash structure. It adds too much visual clutter.

What is the rear shock length and suspension travel?

Mid drives are not outperforming big hubs, unless the trails are very slow and technical. When the trails are nice enough to speed, mid drives are left in the dust. Unless you are talking a 10kw hub vs a 5kw mid on a flat surface drag race then I couldn't disagree more. None of the performance moto...

Bi-directional for regen

This, plus durable and stealthy.

Until a hub is light enough to not adversely impact handling and powerful enough to start on a 30 degree slope the there will be mid-drives outperforming them offroad.

A mid-direct setup with a reduction that could also shift to direct drive (easy with planetaries) would offer some huge advantages.
