    Questions about Crystalyte 5303s

    Hi all, I figured I'd post on this thread as opposed to cluttering the forum with another thread about a really old motor. I've come across a 72v Crystalyte hub motor kit, the hub motor is laced to a 29" wheel and it came with a 72v Crystalyte controller, the APM display, brake levers, rear...

    Is DIY dying?

    Thank you Balmorhea, very helpful. I'll do some research on those.

    Is DIY dying?

    Interesting...so maybe I'm just not "DIY" enough to take advantage of the existing improvements in battery tech. That's something I'll have to explore. Any suggestions on what automotive cells you've had a good experience with?

    Is DIY dying?

    This is my experience as well, although I just have one ebike set up for around town and I don't ride eMTB. The red text is what I am trying to get at. It's been a long wait IMO.

    Is DIY dying?

    My intent with this thread was to gather opinions about the technology advances (or lack thereof) in the DIY market. From my admittedly inexperienced perspective, the DIY offerings for motors and batteries don't seem to have anywhere near the same level of effort from the manufacturers to cut...

    Is DIY dying?

    I think this is a great summation of what I was trying to get at with my original post. I'm not so much interested in "more power" but more the power to weight ratio, both for motors and batteries. My current BBSHD build doesn't need any more power, but if it was significantly lighter and had...

    Is DIY dying?

    Hi all, I don't mean to be inflammatory with the title of my post, but I am interested in other's opinions of the direction of the DIY ebike market. I'm primarily interested in mid drive motors, and it doesn't seem like anything new has come out the last few years in the mid drive market. Most...

    Why fat tires on a street ebike?

    I have a BBSHD on a steel hardtail 27.5+ bike. Currently running the WTB tires that came with the bike when I bought it, set up tubeless. I have around 600 miles on the bike, generally running mostly on pedal assist on bike paths and roads. I always have at least one fairly heavy pannier on...

    Damaged Jumbo Shark - anything to look out for?

    Thanks for the advice all! I have it on a charger now with the bluetooth BMS up, all the cells were still balanced and also appear to be taking the charge evenly. Nothing rattling and no cracks after a bit more detailed inspection. It hit pretty hard though, one edge probably has close to 1/8...

    Damaged Jumbo Shark - anything to look out for?

    Hi all, I let an acquaintance ride my bike around the cul-de-sac, he hit a curb going pretty fast and the Jumbo Shark battery popped off and skidded along the driveway. From what I can tell the battery just got scratched up, there aren't any cracks and the battery seems to work fine. I'm...

    Burning smell from BBSHD at full throttle

    Hi all, I wanted to see if anyone's experienced a burning smell from their BBSHD when under full throttle for a brief period of time. I was coming home from a friends house yesterday and decided to see how fast the bike would go on throttle only. I was on a gradual downhill and had the...

    EM3ev, setting the record straight on a few things

    What you are describing sounds weird to me. I bought a BBSHD kit at the end of April from EM3EV, had it in about 3 weeks. The shipping notifications are a little funky but every time I asked a question they responded the next day. I was never asked for my birthdate. Did you order directly...

    2018 Kona Unit BBSHD Build with questions

    Took a dremel to the battery baseplate. Here is a pic, I used yellow tape to outline the outer edges of the grinding area. I really didn't have to take too much material so I'm not worried about compromising the strength of the plate. The plate lies flat now, it may be a fraction of a degree...

    2018 Kona Unit BBSHD Build with questions

    Thanks, yeah in the pictures I haven’t tightened the motor down yet. Now that I put the Lekkie on I was able to get the main lock ring and the jam nut on. It’s tight against the downtube.

    2018 Kona Unit BBSHD Build with questions

    Well I ordered a Lekkie bling ring and got a much better fit this time around. I only needed 1 3mm spacer on the BBSHD and about 4mm worth of chainring spacers. This gave me a decent chainline although trying to go the lowest gear throws the chain. Pretty sure I don’t need the granny for a BBSHD...

    2018 Kona Unit BBSHD Build with questions

    Thanks for the input, I did a little research and I think I just don't have enough threads to ensure that the lockring stays on even with loctite. I elected to buy a 42t bling ring which has 4-5mm less offset than the Eclipse. In addition it's 6mm smaller in diameter. Hoping that lets me get...

    2018 Kona Unit BBSHD Build with questions

    Hi all, I decided to go with a Kona Unit as the donor bike for my BBSHD build. While I couldn't find any other cases of someone mounting a mid drive on this bike, it checked a lot of boxes for me (standard BB, steel, rack mounts, 27.5+) and I decided to take a chance. I picked up a demo 2018...

    BBSHD mounting questions

    Thanks for the input. I ultimately decided not to go with the Honzo frame as the small front triangle also presented some serious challenges in mounting a battery. It also had no rack mounts. So I sold the Honzo and bought a Kona Unit which seems to have a lot more clearance for the...

    BBSHD mounting questions

    Hi all, I am hoping to mount a BBSHD on a 2018 Kona Honzo steel hardtail frame. The bottom bracket shell is 73mm wide and points towards the standard 68/73 BBSHD. However, the bike is boost spacing and the chainstays move outboard significantly not too far back from the BB. If I just use the...

    Small triangle, big problems. Trying to find a battery that fits my bike.

    I am dealing with the same issue, looking to convert a bike with a really small front triangle. Best option I can think of is the Luna batteries with the new Panasonic GA 3500 cells. I mocked up one of the EM3EV triangle batteries but there will be so little space it'll be tough to do any sort...

    BBSHD Build with GX Eagle 1x12?

    Thanks all, lots of good advice here. I think I've settled on an 8 or 9 speed drivetrain, it's pretty cheap to buy shifters and derailleurs for these. I realize I could just not use the lower gears on the 1x12 but I have another bike running Eagle so I'll keep the spares in case something happens.

    BBSHD Build with GX Eagle 1x12?

    Thanks for the recommendation, I took a look and while their stuff looks interesting, the reviews I read mention that a chain tensioner/guide is usually needed which might make it a no go for this application. I have also looked at the SRAM ebike specific set but it's pretty expensive for...

    BBSHD Build with GX Eagle 1x12?

    Thanks crossbreak, I was leaning towards installing a different cassette/shifter/rear derailleur as I don’t want to experiment with an expensive cassette. I was leaning 10 speed but I will look at 8 speed options, what you are recommending makes sense. Thank you!

    BBSHD Build with GX Eagle 1x12?

    Great advice, thank you! Are you able to shift through your entire range of gears? Can I ask which front chainring you are running?
