    60V 2500W Cyclone Fat Tire eBike 3.4 kWH 16s1p

    Ya, when I had my 72V system, I would parallel two chargers for a 5A charge. Right now, with this big battery it is a bit different how I charge. I rarely charge above 65% SOC and for my local runs even a couple hours and over 20+ miles I dont go below 45%. I think I can charge to 65% SOC at the...

    72V 3000W Cyclone Electric and Gas Generator Build (SBP kit) - Three Phase Dev

    well, the new bike is a fat tire so i am losing tons of efficiency and also i got studded tires. i dont mind though as I am really loving the ride quality of the fat tires. I am usually around 20-25 mph depending on wind and topography. If I am in a rush, I will do upper 20s. Bike can do more...

    My First eBike - I'm Overwhelmed..

    which one are you looking at? the second one is a geared motor with nice lcd display and a ~1kwH battery. I mean this is a really good deal imo. I would be satisfied with that.

    My First eBike - I'm Overwhelmed..

    he wants to ride before the season is over in the midwest. legally? half the bikes on this forum are not "legal". just be sensible and dont do 40 in a 25 mph zone. this shit is not that complicated. pick a motor kit, spend a bit more for quality if possible, buy the biggest battery you can get...

    My First eBike - I'm Overwhelmed..

    That is without shipping. Shipping is like $155 and then I think the kit is still from China they are just a middle man but they can still get it to you in 5-10 days so they say. I know because I asked about the 60V 1500W hub motor from them. If you are going to dial it back, the leaf kit cost...

    My First eBike - I'm Overwhelmed..

    You can get it from SickBikeParts and they have plenty of parts. This motor is fine for that folding bike; you just have to be sensible to not go 40 in a 25 mph zone or do anything stupid. http://sickbikeparts.com/electric-shift-kits-e-products/ LiFePo is relatively safe. Listen all batteries...

    My First eBike - I'm Overwhelmed..

    its also most efficient. wind resistance becomes a big factor at 22. if you have good high psi road tires, you go far at 20. i did irl runs to test it and equations confirm it. though, if i want to get somewhere fast i go fast though i know im using a lot of juice.

    My First eBike - I'm Overwhelmed..

    - Forget about upgrading the controller for this season stick with the stock controller until you learn more about ebikes and next spring - Link where you are seeing these hub kits; I think most are overseas and no way you will get them before the season ends (mid October?). Make sure you check...

    72V 3000W Cyclone Electric and Gas Generator Build (SBP kit) - Three Phase Dev

    Nope, I found the Cyclone to be very reliable though I only go mid 20s cruising and mid 30s top. So, I am not constantly blasting max amps. The motor does get hot after use. Mine makes a rattling sound around the nylon planetary gears but this should not have been a problem if I had replaced the...

    Salvagable or too dangerous - Shorted Lipo Pack with Small Vent Hole

    Its a LiFePo pack from LG Chem, which goes into many EVs. People make DIY powerwalls with this that are literally fastened to a flammable wall. A pure LiPo pack is dangerous I agree but this isnt that. I sealed it back up with hot glue and then taped it but the packaging of the cell pouch is...

    Salvagable or too dangerous - Shorted Lipo Pack with Small Vent Hole

    Sigh, so I frocked up. The crap electrical tape I used to insulate between terminals of my 4s pack somehow came loose and shorted with another cell in the pack. So, it actually was slightly smoking before I was able to pry apart the short. But, the result is one of the packs has a small hole...

    60V 2500W Cyclone Fat Tire eBike 3.4 kWH 16s1p

    Big boy battery time. 16s1p LG Chem N2.1 3.6V 60Ah separated into four 4s1p 60A BMS series back into 60V to fit into Dolomite Fat Tire bike frame. Previously, dodgy low price (cheap) scooter batteries 16 36V 4.4 Ah packs wired into series to produce 72V and low amps like 10A per pack. These LG...

    Insulating materials and methods for battery box

    It is cooling down now but just a week ago it was like upper 80s to lower 90s and sunny. Things baked in the sun. I am finishing a fat tire 3.4kwH build atm and need to make a battery box. I want to make sure this thing is as cool as possible. So far, I have the following plan. - White paint...

    Battery questions - Higher Nominal Voltage and Series Balancing...

    yeh, its a 3kWh pack. I am going to do two 7s1p in series to make 52V nominal. I will attach a 100A power meter to each pack and detach the series connection and parallel them to balance the packs (>0.75V). As you mention, I doubt they get out of balance but just in case I will monitor them. I...

    Battery questions - Higher Nominal Voltage and Series Balancing...

    Hey, I bought 16x 3.6V 60aH LG cells. Originally, I wanted to do a 60V (57.6V) ebike so I can hit mid, upper 30s for top speed. Then, I found it is hard to find different PAS level ebike kits in this COVID-19 era for 60V fat tire ebike and 60V is just not a popular ebike voltage. I also want...

    Got fried by Col. Sanders today. eBike vs pedal

    I just started riding an entry level cheap road bike and the difference between a mountain bike and ebike efficiency is monumental. I was going about 50% faster than on a mountain bike and this is entry level. I trained over the winter but consider myself beginner road rider. Take a look at some...

    Looking for input on my first Ebike build and questions about battery range/usage

    - Your kit has variable PAS so you can set it at level 1 which is like 50W I think and that will basically make the bike frictionless and remove the small resistance from the direct gearless hub - You need to tell us your desired speed and range for battery size; its like trying to give you an...

    Powerful e-bike commuter/runaround for hilly area

    with that bike, the weight would be minimal difference than it would be on the downtube. man, listen, the whole negative about the battery on top tube is by literally guys that never put their battery on the top tube. 7lbs is nothing; lol i have like 35lbs on my top tube. i would say that there...

    DIY vs. Commercial: How/ Why(not)?

    you really need to give us your budget. i totally agree with the posters here; most commerical ebikes are well put together but not worth it for the raw specs. take a look at CYC X1 Pro Gen 2 as a premium motor and nice looking motor + lcd. it looks nice like $$$ nice. couple that with a 1.5kwH...

    Powerful e-bike commuter/runaround for hilly area

    seems good. that small battery you can mount on top tube. i know people dont like it but im fine with it; it looks like a motor bike for me. also, of course you need disc brakes at those speeds.
