Hey all, I have a few questions: I am buying a Blast to make into an electric motorcycle and it has no motor/trans, so I need the measurements to make a battery rack and get the same spacing as was with the motor/trans in it. Does anybody have some measurements for this?? And are there different rear wheel and tranny sprockets (belt pulley's)? so I can play with the gearing? And I also need a rear wheel assembly ? please email me or post here. Any help would be great, thanks, Tbear | ||

The swingarm mounts directly to the engine/tranny. You may be better off with a 'tuber' Buell swingarm and wheel as they used a separate bracket that may be more adaptable for your needs. The wheel would also be better as the Blast only comes in one gearing and a chain conversion is not available as well as any other belt gearing (its also a unique set up, Blast only). | ||

Concur and a Buell tuber chain conversion kit would work at that point. Thus converting your Blast to chain - then your gearing choices increase dramatically. EZ | ||

Yuppers - in a few years, and a spare battery - those things are the future of motorcycling - seen it before. EZ | ||

Say it ain't true. Does it come with speakers so you can play engine sounds as you are driving down the road? I wonder what their plan is for wrecked bikes leaking acid all over the place. | ||

yep, I would definitely want downloadable engine sounds! I don't think Lion batts have liquid acid in them. Tbear, as mentioned above, a tube-frame Buell ('02 & earlier, all models except Blast) wheel & chain conversion gives the most options for gearing. I think there are one or two options for front & rear sprockets with a tuber wheel if you want to stay with belt drive - you'd still have way better tire selection than with a Blast wheel. Anything other than a Blast wheel will require a different swingarm, or lengthening the Blast swingarm. ?Seems like an XB wheel & swingarm would also be compatible? With a Blast wheel, your only gearing option is with the front sprocket. The Blast rear is 80-tooth - way bigger than any other Buell or H-D. You probably won't be able to get the motor shaft centerline as close to the swingarm pivot as the stock tranny output shaft is (how big is the motor?), so a chain/belt tensioner would probably be needed. The XB's have one, don't know about tubers though. | ||

The problem with the XB swingarm is the same as the Blast swingarm-bolts directly to the engine (and it has the oil in swingarm). The tuber swingarm simplifies things. All would work, it just depends on what you want to fabricate. | ||

Tbear, I sent a reply to your email but it was returned, retried several times, figured better to post here anyway... I think the front pulley has 33 teeth, primary is 1:1.67 ratio and 5th gear is 1:1 - at top speed I figure about 3890 RPM at the front pulley, and maybe 20 or 25 horsepower... that's just a shot in the dark though - hopefully somebody here will speak up! What is the HP and RPM of your motor? Are you using some kind of "primary drive" to get the RPM & torque into range? ... or because the motor is too large to get the shaft centerline close enough to the swingarm pivot centerline? What kind of batteries? If you go full OFF-throttle at speed (engine braking) will it recharge the batteries? Could you use something like a chainsaw motor coupled to an alternator as a sort of on-board recharge system for extended range? ...or a wind generator on the front, to recuperate aerodynamic losses on the highway - it could double as a propeller, for extra top-end passing speed! |
