Re: Custom KMX recumbent trike with QS205

At what speed did you simulate 300-500 km range? With your current setup, the drag is probably horrendous. CdA is probably more than 0.5 m^2. Those tires probably aren't very efficient with regard to Crr as well. That is a huge battery pack though. There was a time where lead acid battery powered ca...

Re: Show me your electric velomobile.

Starting with an old Milan is kind of cheating, don't you think? :D Nah. Most of the world's best hot rod builders can make some very fast cars, yet they know nothing about aerodynamics and it is never even a thought nor is efficiency a concern to them, even though the possibility exists for them t...

Re: Show me your electric velomobile.

Impressive, isn't it? On my first ride after the conversion, I could hardly believe the low consumption figures. It is. I remember no shortage of people telling me that the low consumption figures or range I was looking for couldn't be done in a sub 100 lb vehicle. You've gone and done even better ...

Re: Show me your electric velomobile.

Its a simple cadence sensor. If I want a workout and put more force to the pedals, adding assist power as well seemed wrong to me. On the other hand (since the magnets for the cadence sensor are mounted into the chain ring) by shifting down and raising the cadence for climbing hills, or by shifting...

Re: KMX Electric Trike

Did you ever measure your ground clearance? I'm curious to see what the 26" rims up front have raised it to and may later make such an upgrade to my own KMX build.

Re: KMX f-8

Impressive build. I'm glad it didn't kill you. By shifting your weight primarily toward the rear, you've greatly increased your likelihood of tipping over during a turn, especially with the small wheels. The advantage of having had your weight primarily on the front is that you can take corners with...

Re: Show me your electric velomobile.

The Phaserunner is set to 15A, 40A phase current and 10A field weakening. Max power is restricted to 1kW. CAv3 with throttle, PAS, etc. Usually set to 600W max. Is the PAS using a torque sensor or is it using a cadence sensor for its feedback? What kind of power draw is the battery delivering to ma...

Re: Custom KMX recumbent trike with QS205

It's definitely a strange one. I'm wondering what the finished product is going to look like. It's kind of hard for me to see what direction the builder is going with it. So far a lot of the added weight looks non-functional, but that's only because I don't know what the builder's finished product i...

Nice! Really loving the DF air intake and light combo. How many wh/mi does it need to do various flat ground cruising speeds? Top speed on motor only? Acceleration? How is it pedaling with the motor off and the added weight it provides? Has the custom air intake added a noticeable amount of drag and...

Re: Hubmonster 94% efficient 7kw rated $587

Despite the need for better hubbies, the manufacturers won't make them due to cost. Such a wasted opportunity on their part. Better quality steel combined with thinner stator laminations(say 0.2mm) and curved magnets would only add about $100-200 or so per motor... yet the benefits would be enormou...

I was just able to fit the Leaf 1500W motor and a 9 speed freewheel in the back of my HP Velotechnik Scorpion FS26. I had to spread the frame by hand to fit it in and used a number of spacers. I'm a little nervous about how much I had to spread the frame but it was only by hand. Fingers crossed. I ...

Re: New Nissan Leaf.. 50kw more power and 62kwhr battery

The good news: replacement packs, whether done under warranty, or purchased by the owner, are now all "Lizard packs." The later packs will fit the early cars with an adapter kit. So cars with packs replaced after 2014 degrade only as fast as the 2015s, which is the best Nissan ever managed. The REA...

Re: New Nissan Leaf.. 50kw more power and 62kwhr battery

The old Leaf packs from the 1st generation were crap.

Except those CalBs would need twice the space, weigh twice as much, (650kg). and kill the performance. That is quite a sacrifice , and would it save much $$$s ??

Re: New Nissan Leaf.. 50kw more power and 62kwhr battery

Nissan prefers "cheap" over "good" when it comes to battery packs. There is such a thing as "cheap" AND "good" if one is willing to sacrifice specific capacity and energy density, but that will mean the car will have to be designed to be more efficient to compensate for the reduced pack capacity an...

Very exciting to have more options here. I fear that the 1st gen leaf actually left people with a unfavorable opinion on EV cars. 23kwh is way to small of a pack, plus no thermal management. The Leaf's drag coefficient times area was on par with an average full size sedan, so of course 23 kWh didn'...
