Thanks for your assistance...I failed my first attempt with a 48V to 12V DC DC convertor rated at 30 amps out, used to power golf carts. It ran for a while, but failed when my Minnekota was run at 100% for several minutes against a tidal current. I suppose if I hooked up two DCDCs of this size, it m...

I would like to use my big ebike packs to top up (in real time as I am trolling) an AGM gel cell 12v Battery...Can I just run the ebike pack through an MPPT charge controller directly to the AGM pack in parallel, along with my trolling motor from the AGM pack, as I am running the motor? Assuming the...

I have a Bob trailer that I use on my non-suspended tadpole trike for camping gear and it works very well in the forward direction, efficiency-wise. However, they do have a bad tendency to jacknife if you "back up the truck" which I imagine would be a problem for folding joints on a trike frame, pos...

I've read too many Bafang Middrive horror stories and issues to imagine that there is any comparison to the robustness of a simple hub motor system. Why do people bother?

Usually too wide to fit on a bike path as well. The posts on bike paths to slow bikes down at road crossings seem to be set about 40 inches I think - that works well with my trike which is 32 inches wide, but I have to pay attention at speed, which is what the posts are for. That gives me about 4 in...

Not sure if it helps as each trike is a bit different, but on my Performer etrike - a very similar build to yours, with batteries under the seat, and rear direct drive hub motor, I find that 1/16" toe-in is just right. Either side of that even a 1/16th affects the handling. You got it right with you...

My friend bought one of the EM3Ev packs from here in Nanaimo British Columbia Canada, and it arrived safe and sound in about 3 weeks. Its 14S7P. The BMS app works nicely on his phone via Bluetooth, albeit a wee bit primitive. Getting insight into the exact millivoltage of each of the 14 cell groups ...

Sounds like a good time to make a long term investment in airlines, as fossils plummet, leading to cheaper fuel supply. The price of fuel will drop very fast as EV disruption occurs as the daily balance between consumption and production will create an endless overhang of stranded oil biz assets, an...

I understand that village scale sodium based flow batteries are only a matter of a few years away based on the recent discovery at MIT with metallic matrices. They are aready at 150kwatthours/kg. with really long life span. Lithium isn't the only horse in the race.

At the risk of betraying my bias on this one, based on personal experience with my recumbent trike, I am convinced you can't beat the simplicity and functionality of a simple powerful hub motor in the rear wheel. Elegance is the reason. I don't like putting power through the drive train for good rea...

Check out this page...small front hub motor...I think it would work well on the Downtube, with nice balance with a battery on the back rack. Grin is lovely to work with and they are probably the most knowledgeable folks around when it comes to small hub motor solutions for a variety of bikes. I have...

I had a very similar Giant Revive DX conversion a while back, with a front 9C on it, and kept the rear end cassette and pedalling capability. You would loose your front disk brake probably if you did that. I replaced the stem with monkey bars. The twitchiness was substantially reduced with the motor...

I use one of these with Marine Waterproof speakers...2x20 amps...small clean sound and runs nicely off an ebikes.ca 12V DC convertor (from 57Volts downconverted)...

Darn good sound for the money

Hmmm...my Cannondale Hooligan 8s have normal rear 135QR axle setup. I have a nice little front Cute 100 on one of them. The other, I left unelectrified for grocery runs. Awesome bikes but hard to find..

My trike is happiest at exactly 1/16 inch of "toe in". I use an old rabbit ears type tv antenna (one of the extensible halves) to transfer the reading from the two front points of the two front tires to the two back points of the wheels, at the same height above the ground, to measure the exact diff...

Rassy...regarding that wobble/shimmy you referred to...on my Actionbent trike I put a couple of suitably sized greased o-rings inside the headset caps on either side, which gave my steering/headsets enough "stiction" to remove the same shimmy I had on my Actionbent (Taiwanese trike like the Performe...

Incidental to this question, I successfully ran a Minnekota40 Maximizer off my ebike battery for several hours before my 48volt (nominal) to 12 volt DC DC converter (which output 12.1 volts - not enough to charge an intervening AGM battery) before the DC DC went up in smoke bucking a 3 knot current ...

I think you might need the BMSBattery KU63 controller which I run fine on my Q100 motor.

This is an interesting thread for me, as I have been running sensorless for over 19,000 miles for over 10 years on the same motor, same controller. The motor never fails to start up with more than .10 (guessing) mph of forward travel of the bike, and has never unexpectedly failed me. Its just a plai...

I'm not sure if you have ridden the bike, but generally this bike geometry is quite inefficient compared to bikes where the bottom bracket is at the same or almost the same height as the seat, or compared to a normal diamond frame mountain or road bike. So you will REALLY be needing the electric ass...

I recumbent trike tour on a medium power Nine Continent 2806 rear motor . "Medium" to me refers to a power range of maybe around 1500 watts. Above that is "above medium" from my perspective. Oops...Nine Continent 2706 rear hubmotor. http://www.ebikes.ca/shop/electric-bicycle-parts/motors/m2706rd.htm...

I recumbent trike tour on a medium power Nine Continent 2806 rear motor on 26" rear wheel, with a 30 amp controller and dual 48/15ahr packs running in parallel. Peaking at 1400 watts on the CycleAnalyst with a total vehicle/passenger/gear weight of around 280 lbs, and an additional weight for the BO...

Scooters of this sort are illegal in British Columbia...I would be surprised if this were different in Alberta. I built a scooter from a standup kid's bmx type scooter in British Columbia, which was a blast to ride, until I reviewed the legalities...

19,000 on my CycleAnalyst since 2008. Actionbent alloy recumbent trike. Equivalent to Performer JC70 trike, Mesh seats.

I believe that what I have learned over the 19000 miles on my etrike CycleAnalyst is that rigidity is your friend when concocting an etrike. Anywhere that rigidity is lost could be a problem. I have eliminated all sources of rigidity loss possible, in any masses on the trike concentrated at large mo...
