This is an excellent bike to fit a BBSHD to, easy to do, only hiccough was I needed to file bottom bracket a wee bit to fit motor through. other than that straightforward. The Nexus 3 is an excellent pairing for the BBSHD with a 42t leckie ring alike. you get amazing hill climb ability in 1st. 2nd for most flying around town or trails and 3rd for some top speed on the open road if you want to hit 30mph plus. Could do with a thudbuster seat or suntour though as no suspension is a pain in the ass - literally.

Update, just bought an asi bac 855 controller with nxt display, with a 72v battery this things gonna go like a rocket. Yeehaa. -
Ncrkd. No no problem, BBSHD just went straight on with no spacers and cleared frame fine at just the right chainline. Such an easy bike to do this to.Comment

I Didn't put the nexus hub on, the bike just came like that standard so didn't have to worry about clearance issues or anything. The bike was only £400 so by time I bought battery and BBSHD I only spent around £1300 in totalComment

If the Dee had been in stock I'd have built it instead of my Gravity DeadEye 27Plus. That or a Marin Presidio 3, or the Giant MomentumUX. Pretty bike! Best of luck with the build!Comment

Thanks DCErik, is your gravity deadeye 27 on here that i can see?Comment

Still in progress, but I'll post up something here once I've got something to show. If you're into all the preamble, I've been posting it here: https://electricbikereview.com/forum...me-down.34489/
Haven't even ordered the BBSHD or battery yet, but my heavy-duty chain should arrive any minute now, and I've got a set of Kenda Havoc Pro 27.5x3 50km/h rated tires inbound that I found for $49 each at bikebuys. Ordered a Sturmey Archer RS-RK3 hub from universalcycles before realizing that they have a very comprehensive and affordable wheel building service, so arranged to reject the delivery and have it returned to them for inclusion in a wheelset. It'll take a while, but I can acoustic around on the mediocre stock wheels until then!

I'm running a 40t chainring and an 18t sprocket on my Sturmey RS-RK3 hub, and find that I'm ghost pedaling above 27 mph or so. I can make 32 or so on throttle in 3rd, but haven't touched the throttle since August. At 52v the BBSHD makes a disappointing e-scooter. Are you able to pedal at speed on your 70v rig?Comment

Hi DCErik, upto 30mph I can peddle in 3rd okay, above that I am ghost peddling. If i want to use peddle assist to go further I stick it in 2nd or 3rd gear and pas 4 on eco and that has a nice feel for peddling on the flat. Usually though I just use throttle and can go over 40mph in 1st and 50 if I go upto 3rd. Don't do that though really, just normally keep it in 1st. I only tried it the once just to see what the top speed would be at 3000w. Pretty scary with no suspension at 50mph on a pushbike, 40 odds in 1st is plenty fast enough and theres no straining the nexus.Comment

Wow. You must be running a larger chainring, or a smaller cog. The smallest available cog for the SA hub is a 16t, but it's not dished and my chainline is already pretty woeful due to the Bafang 40t being pretty flat. Think I'll go to the 42t Lekkie, as on the stock 46t I could pedal up to 27 or so on an 18t cog. Thanks!Comment

DCErik Yeah 42t on front and 18t on back is what I have. I should have said that getting up towards 30 my legs are flying around just a blur, I made it sound like that that was easy but we are probably similar with you at 40 and 18.
There's a guy here in UK has leckie ring alikes but a lot cheaper, that I use. I did buy a 23t rear sprocket to let the bbshd run faster and cooler and to just leave it in the strong 2nd gear but motor seems to be okay heatwise and had no probs with 1 st gear the way it is just now.

`How you used that hose clamp to mount your battery? Got any pictures?Comment

Laissez Soz not got a pic but it was easy on my batteries base as there was slits at either side of the bottom of the base you just fed the clamp through and it straddled the plastic bar in the centreComment
