Thanks Neal. Is that with the 350w motor and can you buy front chainrings for the BBS?

If that's the Tour of New Zealand, then they sure have a lot of fat cyclists and no crowd coverage! My guess, is that it's an amateur Sunday event. Made me laugh and thanks for the bike calculator Tony. Thanks for ALL the info guys; much appreciated & Michael: build that bike!!! Sooooooo, am I right in saying a 350w motor will give more power on the flat?

Thanks Michael What's the top speed of the 250W Bafung 8fun crank drive, with a 36V 15Ah battery on the flat, and how long can it hold it for? Do I need the additional brake levers and throttle? Are they worth the money? ps. Michael; hurry up and build that bike - I wanna see it!!!

Thanks d8veh and Nealh d8veh; earlier in the thread , you said: "A crank-drive motor or the 2-speed Xiongda hub-motor would be a better solution because neither suffer from low-speed over-heating." The Xiongda is out (I'm not stretching a new frame!!!) so I guess it's the BBS01 on an Eastway bike. Michael stated: "I'd have to say that a BBS01 straight out of the box meets all of those requirements. It will do the climb. It won't overheat because you can use the bike's gearing to allow the motor to spin at speed even whilst climbing slowly. It does of course fit 130mm rear dropout! It delivers over 500W straight out of the box even though it states 250W on the inscription plate. It won't rip a 700c wheel apart - it is very smooth in its power delivery. It is also very quiet and easy to install." As I don't want the missus getting nicked by Le Plod, I guess this is the best option for me (and her!). She will climb slow (so will I for that matter). Hence this seems the best option, I guess... anotherkiwi added: "A 250W Bafung 8fun crank drive, with a 36V 15Ah battery, set to high assist mode will get to the top. Your significant other will have to pedal all the way but with little effort according to the calculator I posted a link to EDIT: did I say "no throttles allowed"?. the calculator says the pedelec can do it in 1 hour 12 minutes with a "lazy" rider or 58 minutes with a "fit" rider." Again, this seems to have swung in favour of the 8fun and I'll stick a 30 sprocket on the back. Can I stick a 48v battery with it? Thanks all, this thread has been a great help to me. Now, where should I get it from???

Awh GAWD!!! Now I'm all confused again!!!! Thanks for your help Michael! I am listening to everyone!!! BTW, whats a BPM and whom makes it?

Thank you

Thanks again Michael May I ask, if you've got the bike going (yet!) is there any flex around the bottom bracket area with the bike being an alloy frame? Interesting reading from d8veh. It looks as though the missus will be cycling the mountain a few hairpins at a time! Re. the BBS02 Does anyone know if it's got the wattage stamped on the outside of it? Is it OK to use it with v brakes? I've got another ol' Kona that I was going to use with a crank drive (see pic). It's steel.

Thanks Michael, expect a message soon and I'd love to see the bike when it's built, if that's possible? Do you know the top speed of your build?

Jeez! That looks like the Millennium Falcon's warp drive to me matey! I'm based in Crawley. Let me have a butcher's at it and I'll get back to you. Cheers

Thanks Michael. May I ask; what size battery are you using?

Good calculator. Thanks anotherkiwi

selrahc1992 - Please start your own thread. It's hard enough to get an answer to my question! Hugs 'n' kisses xxx

Michael, how do you go about upping the power to 350w? Please remember that I am a newbie to all of this! Although I've been around bicycles all my life, I know diddly-squat about pedelecs! Hmmm, this is where I get a little bit lost! Of course, everyone has opinions to what it the best "this 'n' that", and it seems that just when I'm at the point of ordering the bike and bits, I get another piece of advice! My shopping list is... 1. A motor that can go up distance to the summit of at 1,860 m (6,102 ft)) is 13.8 km (8.6 mi), with an average gradient of 8.1%, with 21 hairpin bends and a maximum gradient of 13% with an unfit rider attached. 2. A motor that won't overheat. 3. Can fit a 130mm rear dropout (if rear wheel attached) Yes, I know that's near impossible! 4. A motor that delivers 500+w, even though it says 250w on the tin. 5. If it is rear wheel drive; preferably a motor that wont rip a 700c wheel apart! Answers on a postcard please...

Thanks Dave, I do appreciate the advice that you and everyone has given on this forum That new XD Double-speed Motor looks interesting!

Could I stick a Xiongda in one of these?

True, but busting a brand new bike is pointless. Do they make the 135mm motor in 740w and will it be too powerful for a 700c rim? edit: Ah, just seen that the 135mm motor is no use for the Eastway as it can only use disc brakes. Maybe, I can get an old MTB frame of ebay, that I don't mind breaking!

I'm not sure I would want to stretch an Eastway XL frame to 150mm!!! Do they make the 135mm motor in 740w and will it be too powerful for a 700c rim?

Thanks guys; this was the kind of info I was looking for. My girlfriend is unfit. end of. I'm starting a training programme for her tomorrow. Fourteen years ago, I did d'huez in 51 mins riding 42x23 on a Paganini steel racing bike. Fourteen years later... The 2-speed Xiongda looks good. I'm just going to see if it will fit the Eastway as it's 135mm wide. Here's hoping! I read an article on it here: https://www.electricbike.com/2-speed-e-matic-xiongda/ and thanks for the additional info d8veh. Can it fit with a disc brake? I like the fact that the 48V version actually supplies 740W, but…it looks exactly like the EU legal 250W version! I don't want my gf being nabbed by the Le Plod. back online laters...

d'huez is a bit of a beast. I've done it a few times whilst touring and on my racing bike. It hurt every time. I know my partner won't make it on her own, hence the need for an electric bike. Re. "Almost any motor will do the job for you" It seems I'm getting conflicting advice here. I've spoken to other electric bike sellers, and nobody can give me a straight answer. Yes, everyone has an opinion, and I'm grateful for the advice, but...

Thanks for the info, but it's a bit gobbledegook to me!!! I wouldn't put such a motor on the front forks, as the missus is riding it. Re. Batteries: I'm just going with what you guys are telling me, as I know jack about electrics etc. ha! May I ask, would a 48V 750W BBS02 be better or has the 36V 500W BBS02 got more torque for the mountains? Remember, it's Alpe d'huez AND the flat for when I come back home, so I need a bit of an all-rounder. Not asking for much am I? You can get a BBS02 for a little over £400 offa ebay now, and the listing states that it can do 45mph! Is that possible? I couldn't imagine that speed, even with a bloody strong wind behind you and a can of beans! This means I could make the bike for around £800... Oops, oh yeah; I need a battery! What make/model ?

Thanks for the info guys I was looking at 29ers, but they all seem to have suspension forks in my price range, and I see them as an added weight to carry. As the bike isn't going to see much dirt, I was thinking of one of these: http://www.wiggle.co.uk/eastway-fb40-2014/ My question is, would the motor, a 48V 500W BPM with 48V 15AH battery and 25A controller, be too powerful for it? ps. I would fit wider tyres... (yes, I know about width and rim configs! )

Hmmm, this is getting interesting now... I'm considering getting a 29er, so we can both use it! Me for the coffee shop and 'er indoors for longer jaunts. If I'm going to spend that amount on the 48V 750W BBS02, I may as well get a new bike So it's; Low speed =better hill climbing without over heating, or high speed = not so good at hill climbing and will overheat on hill? I need speed+hill climbing, so what's the best 29er or 700c for under £1k? ps. no fighting now chaps!

Yup! Can't disagree with what you have said, but this will get the missus out of the house and she can't complain that we don't spend any time together! If I can get 25mph for an hour (with pedalling) with a Cyclotricity kit rear drive 48v 500W-1000W hub, then I'll be happy. Is this achievable...?

This pic is the same bike, but my missus' bike has alloy straight forks. We changed them as they were too heavy. I guess the Bafang looks the best bet, but with the battery, £500+ notes is a little out of my price range. I couldn't put a motor on my tandem. Maybe when I'm a little older, but not now, as I'm too much of a purist ;-) BTW: Thanks for the replies. Keep 'em coming!

Hi, I was wondering if anyone could give me some advice please, regarding converting an old Cinder Cone for my girlfriend? We're hoping to see the Tour de France on Alpe d'Huez this year, and as we usually take the tandem abroad, I'm getting a bit fed up dragging a tandem over the Alps/Pyrenees (with an ever reluctant to pedal missus on the back) so this year, I thought I would treat her to her own two wheels (she has got a bloody nice bike actually, but gives up on hills) with electric assistance. After the holiday is over, I was looking to use the bike as a derny for my training. I have a tarmac road (not mine!) which I can use at work, so I'm looking to create a fast bike, for little money (aren't we all?) The bike will be transported to France on the roof of my car. We're not riding there!!! I know nothing about electric bikes and this is my first post, so please be gentle! Thanks in advance! ;-) Scott
