I agree, be cautious more than anxious. Imo, you could likely make a much nicer build diy, for less money. As a firsttimer, maybe don't plan to save much money, but get alot of experience which will help to use/maintenance/upkeep.
I did my first diy this year, and just grabbed a purpose built frame for another in the future. Eastgem on aliexpress also has frames and whole bikes.
Imo I'd get just a frame and try to source the electronics (including hub) from the most reliable(1) economical(2) local(3) place. A retired ebay or local DH bike could offer all or most of the other bike parts at a good value.
That said, that's me, and if you have some semblance of buyer protection with endurobike, they're likely to come thru for you as advertised. Add up the component prices as a fun exercise before buying? Really its just a naked bike with a hub, yes? Price seems reasonable, but a little steep for a diy'er?
You're doing all the ebike diy anyway if you have to supply controller/battery/computer anyway?
On battery: 6x4 5s lipo for the battery? 20s 6p is huge isn't it? I run 20s2p 5800mah for 1-3mi/ah on a ~70lb 6kw build. more than 2p is alot of range, but also alot of lipo.
imo large packs are best suited for can-cell bms'd storebought batteries. The main benefits of lipo are just the highest draw in the smallest/cheapest package.
Curious to see how you make-out. Goodluck and welcome to the ebike world!
Wow how interesting to see my complete thought process laid out by someone else and not 2 much longer after I had to go through this whole DIY process basically alone, obv except for advice on ES (It's actually what I told the Factory when only buying the Frame!) Shipping a bomber or Vector back to E Europe for repair is bad enough! but we all know what Chinese warranties are worth
so a home DIY build was the only way to know my whole build inside out for repairing issues that arise.
Your 1st and 2nd points, while initially appearing conflicting, are also well taken, for while it seems one could indeed make one's own superior "Build," for cheaper, (e.g using new bike, take-off's,) in practice, as a 1st time build it was actually slightly more pricey @about $3.5k costs but all my labour and time.
I also was able to design a custom bike setup on the frame, using a far bigger 76v Lifep04 prismatic of 30ah not 20ah with a max 8c not 5c rating that I had custom built for me. I also chose the Lyen 18fet ESC rather than a base Infineon 18fet or the Sabvoton Sine wave, they now offer, and I use the higher version CAv3 (the Factory said they were out of CA v2.3 when I ordered the frame 8 months ago and didn't even know when to expect more and advised me to buy in the US, around about when I found ES, and joined, so that wasn't a prob
I was also able to use this forum, to find myself a better DD hub that matched my needs, that's @the same time, fast, powerful and more efficient/economical for my larger (way heavier and slightly bulkier too,) battery, so as to improve my range, which drains proportionally faster to the amount of power you use, (as well as heating up the hub quickly,) so thanks to user Neptronix for all his pioneering test work on the Leafmotor
My wider battery, meant a further amount of customization to the frame was necessary to accept it, also necessary was a custom widened BB with extended spindle width, to create the necessary crank clearance around the wider box. The original 100mm by 145mm VP components Fatbike BB, was switched for one with a 170mm spindle, and a custom 206mm one that's on the way should fit even better. I've mounted my controller externally, but covered it with a protective plastic enclosure I modified from a rectangular (Thick/tough 3mm+) card file box, to protect it and the wiring into the frame, from stones and road debris.
For convenience and fit I also bought a few components from Leili too, like their new 203mm disks with zoom hydraulic ebrakes as well as their 42t chainring and crankset as well as front rim and 36h hub, everything else was either Alibaba or Ebay/Amazon bought.
As a first build it was def a challenge but I gained invaluable experience from it, learning just how my actual Bike was built and setup, so I'm the best person equipped to fix any subsequent repatable issues, (I hope
I wish everyone all the best with all the diff EEB builds, It's a super fun frame that feels very durable to me so far, and I hope everyone is LOVING IT just as much as I am.
P.S I've had decals for the side covers for abt 4 months now (they're of THFC my footy team, but since we're having a best season in ages, I don't wanna be the public JINX!! so the SPURS EEB will be coming soon...
keep tuned
I don't really have vids or more than random pics and because of winter testing was only 80% complete with my longest run only 12miles
