    Power Wheels Racing

    Alright, some of you are familiar with this and some are not: http://www.powerracingseries.org/ A lot of my friends compete and I'm considering giving it a shot this year. The rules are a little tricky, the total project has to cost less than $500 but that doesnt include the initial power...

    Burning up brushless ESCs

    I've seen a number of people complain that while it's good, it's still a bit too little gearing to handle all situations so I'd like a pair of gears in the front to give me as much flexibility as possible. I'm going to do a LOT of number crunching though to see where this ends up in practice...

    Burning up brushless ESCs

    By input capacitors, you guys talking about this? http://www.rcgroups.com/forums/showthread.php?t=952523 The RC-specific Cycle Analyst is dead sexy BTW: http://www.ebikes.ca/store/store_rc.php -Mike

    Burning up brushless ESCs

    I'm shooting for a "through the bottom bracket" design with a N360 on the rear and a pair of chainrings up front with a tandem chainring on the other side. The motor will be attached to the tandem chainring so I get two gears I can choose from on the front and the N360 on the rear. The goal is...

    Burning up brushless ESCs

    Actually that was very helpful. Many of the people on this forum are pushing the edge consistently and so you see a great deal of horror stories with things burning up, broken down, etc. It's a bit unnerving when I'm looking for something that is pretty reliable. Thanks! -Mike

    Burning up brushless ESCs

    Is the consensus that the Phoenix Ice HV 160 is the best speed controller out there for RC builds? I've read a few people talking about burning them up under acceleration. The idea of toasting the second most expensive component in the system so easily scares me a great deal. I know there is all...

    Tandem Cranks and Associated Questions

    Ok, I feel like a moron asking this, but I'm just not getting it... I've read about people using tandem bike cranksets as they get a chainring on each side. The "drive side" is on the right and can still be geared with a motor driving the left side. This makes perfect sense and seems pretty...

    Any weekend update? I'm eagerly awaiting the results of your testing. You are a terrible tease with all of these updates. :) -Mike

    Thanks again for the response! In addition to the White Industries freewheel, what are you using for the crankset pair of sprokets/freewheel? It's very nice and compact vs. some I've seen on here. Regarding purchasing, what would be included in the whole kit? Thanks! -Mike

    Thanks for the info! Care to share what front freewheel configuration you are using in the end? Sorry to ask so many questions but after all my research, I prefer your direction the most and plan on making my bike similar. Thanks again! -Mike

    Current Cycles Prototype Buildlog...

    I'm sure you said it already, but what gear ratio are you going with currently? Are you assuming an 80% of peak RPM for the motor or something else? I read why the chain and not a belt but why not go gears on the motor directly to make the entire system gear driven? Finally, how does it sound...

    Shimano Geared Hub and Jackshaft?

    Gah, I assumed the Shimano had the standard splines and could support the twin freewheels. I see instead that it has an odd three lobe thing. I hate how few standards there are in bikes! I REALLY want a solution that gives me a fair number of gears or I'll just end up using the motor constantly...

    Shimano Geared Hub and Jackshaft?

    Thanks Rassy; I've read your threads and learned a good bit. So now I'm more confused than ever... If these adapters are available: http://www.endless-sphere.com/forums/viewtopic.php?f=28&t=17602 Then I believe I can just run two of those together on the rear hub - Nexus or Alfine. Is that...

    Shimano Geared Hub and Jackshaft?

    Those threads were pretty interesting and informative. What is the advantage of the SA over the Shimano? I'm a little confused about why to choose one over the other. -Mike

    Shimano Geared Hub and Jackshaft?

    I've got a bonus check coming and I'm going to spend a good bit of the money on high-quality bike that I can use for many years to come. So my first (of many I suspect) question is this: Can I get away with using a jackshaft combined with a Shimano Alfine or Nexus internally geared hub so the...

    Estimating Load/No Load RPM Difference for Gearing

    Thanks! Is that 80% for both brushed and brushless?

    Estimating Load/No Load RPM Difference for Gearing

    Hi all; I was wondering if there is a rule of thumb to convert the no-load RPM to a real-world loaded RPM for the sake of creating proper gearing. I have several motor options, one brushless and one brushed and I know the theoretical RPM of each but that's always no-load. I want to design a...

    Is This Motor a Good Choice?

    Thanks for all the comments. The rules are getting modified for next year, the big ones are that no one can race with lithium chemistry batteries - lipos are specifically called out, people are still arguing lifepo stuff. SLAs, nicad, etc. are all fully supported. There were a fair number of...

    Is This Motor a Good Choice?

    I have the controller + motor already but it still counts against me. The price is something like 150 vs. 200. I have 9 months to build the kart so out-of-stock isn't an issue at all.

    Is This Motor a Good Choice?

    Hi all; I'm competing in the Power Wheels Racing Series next year for the heck of it and a chance to get better at engineering and machining. With that said, I know of no place with more experts on electric vehicles and motors than this forum so I figured I'd ask for some advice here. This is...

    The topic listed no longer exists: http://www.endless-sphere.com/forums/viewtopic.php?f=9&t=11877&p=180070#p180070 Is there another place to go for these? I'm really hoping to not have to make my own. Thanks! Mike

    Best Long Range Option

    Thanks for all the suggestions! I'm set on building the Delta Wolf as I like the looks - I'll be done building the frame today actually. Due to large rear wheels, extra-wide hubs, and a super low center of gravity, it handles extremely well at speeds already so I think I should be fine there. To...

    Best Long Range Option

    Hi all; I'm currently building the dead-sexy (at least I think so) Delta Wolf trike from Atomic Zombie. It looks like this in case you've not seen it: From my previous electric project, I have two 1000 watt Unite motors and controllers from TNCScooters as well as four 85 amp hour deep cycle...
