    Calculating Mid-Drive drive train ratio + nuvinci. How?

    A Surly Singleator can help give a good wrap on a chain, has plenty of latteral and tension adjustment, $50 well spent if it works, I love mine.

    AVE XH-9

    Just passed the 900km mark and the Rohloff on the rear proves to be a good combo. I swapped the rear tyre back to the stock item and it is easier to hit 45 on the flat. Gears 10 through 14 are all that generally get used on the flat. Few new parts swapped out for lighter items, seat, seat post...

    AVE XH-9

    Managed to get the chain to stop skipping by using a 7 speed chain and stong tension on the chain tensioner, so far so good. The Rohloff adds a bit of weight to the rear wheel which is noticed carrying the bike but not really riding it. The meaty rear tyre adds a bit of rolling resistance so it...

    Dogati Electric Superleggera

    I vote for a custom riser bar that would do such a great bike justice and integrate lights and CA holders onto the bar.

    AVE XH-9

    Installed the Rohloff rear hub with a Surly singelator chain tensioner. The gears work but it slips chain on just pedal power... I think the single speed rear sprocket may not be compatible with the chain I had on there, despite good wrap and tension. Also tried removing the crank arm to do...

    AVE XH-9

    I recently enjoyed clocking up the first 500km on the AVE xh9-s and can honestly say I am still really enjoying it. The stats on the screen are currently: 514 total distance 55.4 max speed 26.5 average speed 19:27 elapsed time The only issue I have is a couple of near death experiances which...

    Project Cove GNG-Spot build thread

    That is a great looking bike to start with, electrically assisted, it is going to be very sharp indeed. Really looking forward to see it evolve; great fabrication skills on the mount, is that the work of a well programmed computer or a patient perfectionist with a drill press and a file...

    GNG, 1000W 48V BB-drive, $400

    Just in case anyone was curious how a GNG motor might look inside a Greyborg frame. Just waiting on a few upgrade parts from LR to complete the install. The canopy will need tweeking but it should hide all the trouser catching spinning bits quite safely.

    AVE XH-9

    I am approaching the 200km mark on the XH-9s and so far so good. The bike is still behaving and I have had no issues with it in stock form. 45kmh is fast enough for me, 95% of the time I find. The multi level assist works really well and is intuitive, the battery range is huge on minmal...

    Great work Lightning Rods, the kit you are offering looks like it will rock. :D Now, who was it that said "you can't make a silk purse out of a sow's ear" ? An ancient expression that I believe you have just proved wrong. Looking forward to seeing the real world tests; this has just moved...

    AVE XH-9

    I have been enjoying the AVE xh9-s in stock form, I was encouraged to cycle every night after work for an hour or more and that is unusual for me. It is a great inducement to get outside and get some fresh air. I would recomend the bike as a decent turnkey option. But since there is a need for...

    AVE XH-9

    The AVE XH-9s arrived yesterday, it arrived 95% assembled in a big box. Only the handlebars needed to be tightened, pedals installed and the computer screen clicked into place. The battery is the 400wh Bosch type with a 4 amp, 36v charger, it is a tidy battery. Once the battery was charged from...

    Zerode G-1

    I happened to spot an old unwanted Zerode G-1 frame on Ebay yesterday..... $1600 starting bid, good condition, frame only..... Apparently, mine was the only eye it caught :D Next year, if the Gods are smiling should see an E version on the Sphere.

    AVE XH-9

    My new bike arrived, I took it out of the box, tightened a few nuts and bolts, charged it, installed the pedals and took it for a spin. The build quality and components are great, the bike was light, less than 22kg, and fun to ride. I did notice that the pedal assist died off at 25km, flat out...

    Renamed: Kona Coiler Custom

    Nice bike, looks really practical. I am looking at getting a 48v BMS from the guys at Bestekpower, I have not got it yet so cannot vouch for quality but they do sell the larger voltage BMS. Might be worth a look at least. http://www.bestekpower.com/20sto26spcmbmspcbforli-ionli-polymerbatterypack/

    Samples here-Flanged GOOD Quality FW's w/dual Row Bearings

    Thank you Miles for reminding me of the "freewheel museum" thread, it was but a distant memory. I will have to re read it again in all it's glorious detail.......

    Samples here-Flanged GOOD Quality FW's w/dual Row Bearings

    It pains me to see that there is still not one free wheel producer that can see a niche in the market for a dual row flanged freewheel. Tensile make a 60 click freewheel with dual row bearings, fully servicable and decent quality, available for 37.50 from Tarty Bikes. They sell the outer ring...

    New Bosch Motor.

    The old bosch motor seems pretty good, the newer one should be even better. For a person that wants to build their own DH E MTB without access to a machine shop, this is not a bad option at the price. http://www.orangebc.com/de/produkte/antriebssysteme/AVE-xh11-Framekit.html There is a bike...

    Haibike EQ Trekking, Bosch drive.

    I spoke to a bike distributor sellinging one of the 45kmh Bosch EU Fast Pedelec about changing the rear wheel to a Rohloff. If you tell them in advance, they will change the gearing at the sprocket so that the 45Kmh top speed is maintained. If you neglect to mention it at the time of purchase...

    GNG, 1000W 48V BB-drive, $400

    Hi Ferret Sounds like you have an intresting plan. I bought the parts you were looking for from Matex a good while back, they will probably eventually reply as they did to my web request, I was also going to copy the Dogati setup but ended up in a different direction. I seem to remember the...

    GNG, 1000W 48V BB-drive, $400

    Some of the finest RC reduction drives around, that Matt "Recumpence" has created, use a primary belt and secondary chain setup. There is sound reason, practical realworld experience and considered logic behind his choices. You are barking up the correct tree. Look forward to seeing how the...

    Which right angle gearbox for a 80-100?

    Check out Apex Dynamics offerings. They have a right angle compact model with a pulley which is neat. I wanted to buy one, but they did not want to sell to me because I was unsure of the input shaft size. www.apexdynamicsusa.com

    GNG, 1000W 48V BB-drive, $400

    Hi Mike My plan was always to get my Greyborg up and running at 48v with an Astro 3210, 10 turn, and Matts 2 stage reduction drive. This now works just fine running through the gears in a Shimano Alfine 11 speed rear hub. I just have to pedal to get it going to avoid synchronization stutter and...

    GNG, 1000W 48V BB-drive, $400

    Hi Kifukarider I have done zero miles with the stock GNG setup, strange as it may sound, I want to improve it before I have even used it! I have a different motor setup at the moment and want to fine tune that one first, then do a back to back comparison. The GNG is back in a spares box but...
