Hi RoyL, I run 42t x 16t my tyres are big apples 2.35 on 26" rim. You can work out the gear inches on sheldon browns calculator I find they mean more to me than percentages. My bottom underdrive gear would be too high for me without motor assist but my full overdrive gives me a good top speed...

I live in a hilly area and have built a 350w and a 750w both use Nu Vinchi N360 and Harmony electric shift. My girlfriend loves her 350w bike it does the job, had I not been able to do a direct comparison the BBS01 is adequate especially if your riding is fairly flat. The BBS02 has the extra...

Hi Go-Coo, That sounds promising I may get a chain glider before winter sets in. Been very indulgent am setting bike up with dynamo lighting system, and have upgraded brakes with ice tech pads and rotas the front now 203mm up from 180mm fantastic stopping power wet or dry. So will pass on offer...

A nice looking build Go-Coo glad ur enjoying the BBS 02/ Nu Vinchi combo they work so nicely together, I run my controller on the 9 step power setting, It gives finer control and use of the motors power. How do u find your chain glider is it noisy I can't decide if I want to fit one if it's...

Really have not got to grips with the Speedict full fuctionality yet and only use it for accurate mph and batt voltage readings will be fitting the temp probe soon after reading a useful link to Electric-FatBike.com in Go-Coo new thread. It will prove interesting to see how hard/hot the motor is...

Hi Go-Coo, Only got chance today to take some pics of wiring on my girlfrends bike I finished a month ago, this uses a 36v BBS 01 so the 36v battery is within the NuVinchi harmony voltage range 18v to 50v. The power cable has a spur lead soldered in going in opposite direction...

Very interesting post would add to the mix crank length in improving your pedaling smoothness and efficency I use 165mm cranks the standard cranks with BBS 01/2 kit are too long for me. My natural cadence is about 75 rpm, I use Nuvinchi N360 with Harmony gear shift I set my cadence to my desired...

Enjoy ur build looking forward to seeing pics and info of your finished build.

Hi Go-Coo, Thanks for the links checkout www.tritoncycles.co.uk for deals on krampus frames, would guess they are more expensive over here plus shipping making them even more so.

Hi Go-Coo a few more pics the pair of 6S Zippy lipos I use fit easily into this small carradice canvas saddle bag, this is prob it's most stealth look, in general tho I keep the rack and useful panniers fitted. The selle anatomica saddle was a recent and more comfortable for me replacement for...

Hi Go-Coo, Thanks for you nice comments the N360 hub and harmony gears are still working fine no issues to report as yet, I am mindful that people say the BBS 02 750w could damage/overtorque the hub, I don't abuse it with full thottle standing starts etc. My local rides take in some steep hills...

Hi All, Just an update I built up my girlfriends bike using a BBS 01 350w with NuVinchi 360 and Harmony electric shift she uses it to ride to work. A long hill she has to climb "approx 1 mile" on the ride home she now averages 12/15 mph without puffing for breath, on her non assist bike she...

I am running Nuvinchi with a BBS 02 750w and harmony auto shift its all working fine so far I only ride for lesure tho so no real mileage built up yet to assess reliability. Am now building a BBS 01 350w version for my girlfriend to use, will be interesting to try them back to back for...

Great info on long term performance of the N360 Denman I share your preference for how the Nuvinchi changes gear over a derailiur.To me adding the harmony electric shift mech has really shown what the Nuvinchi can do other shift systems can't do, you simply pedal along at your chosen cadenence...

You can buy a BBS01 kit with 14.5ah battery for about £600 in the uk prob better suited to mountain bike riding off road, if you prefer a front hub set up take a look at the Ansmann front hub drive kit. I rode one at bike show a couple of years ago it was very nice I almost brought one, they...

Worth trying bike shops that deal in tandem kit, I found my pair of tandem cranks at sjscycles.co.uk in England I was not very pleased with the finish of the thorn cranks and thought them badly finished and poor value for money at £25 each. I emailed SJS with pics of the swarf around the threads...

Thx Louis the pashley is a nicely made bike we picked it up 2nd hand it had hardly been ridden,there are plenty to chose from over here we only live bout 15 miles from the place they build them. I will set the rear brake a little slack to facilitate cutting the power for gear shifts I doubt she...

I ordered one those chainring adapters a couple of days ago glad to hear the quality of them is good. Am converting my girlfriends Pashley Princess sovereign to an ebike with the 350w BBS 01 kit I took off my bike. Am hoping this chainring adapter will allow me to fit the fully enclosed chain...

If your not familiar with working out gear ratios sheldon browns gear calculator is an excellent tool, I work out what I need expressed in gear inches, it's more meaningful to me than percentages or gain ratios. My bike pre electric conversion ran a 9 speed cassette and double chainrings, my...
